The Best Lego Sets For 4, 5 and 6 Year Olds in 2020


We started our family Lego collection when we had a 5-year-old and a 3-year-old. At 3, you have to watch them like a hawk to make sure Legos aren’t swallowed, but we have three kids who love playing Legos now.

The preschool through first-grade years is the perfect time to introduce your child to Legos. It can be overwhelming to know where to begin amidst the thousands of sets, so I’ve compiled a list of the best Lego sets for 4-, 5- and 6-year-olds.

I’ve split the recommendations into each age group, but many sets would work for all three ages. If your child is new to Lego, I would recommend starting with the kinds of sets from my 4-year-old list.

The Best Lego Sets For 4-Year-Olds 

LEGO Classic Medium Creative Brick Box

LEGO Classic Medium Creative Brick Box 10696 Building Toys for Creative Play; Kids Creative Kit (484 Pieces)

The LEGO Classic Medium Creative Brick Box 10696(484 Pieces) is a great place to start your collection. It is a bin of almost 500 Lego bricks and pieces of various colors and sizes.

Though there are a few instructions for small models you can make with those pieces, this set is much more about letting your kid be creative and make whatever they want. That’s especially important at early ages.

Following Lego directions might be hard for your 4-year-old. Lego directions are all visual. You can find examples of Lego instructions online if you aren’t familiar with them. There isn’t any reading to do; you just follow the pictures. But it does take attention to detail. So having a bunch of loose Legos to just build with is a great start.

We got this exact set in our first round of Lego buying and it was great. Our two oldest had hours of fun building whatever they thought of. The oldest did follow the directions for a few things.

The bin is also great for Lego storage. The bricks that come in it do not fill it up, so you have room for creations or additional pieces as well.

LEGO Frozen II Anna’s Canoe Expedition

LEGO Disney Frozen II Anna’s Canoe Expedition 41165 Frozen Adventure Easy Building Kit (108 Pieces)

The LEGO Frozen II Anna’s Canoe Expedition 41165 (108 Pieces) will be great for your 4-year-old Frozen fan.

This set comes with 108 pieces and visual instructions to turn them into a canoe and landscape for Anna and Olaf to sail past and play in. There’s a slide and seesaw and a bunny in its house.

These sets that are for ages 4+ are a nice introduction to building sets. They took the place of a Lego Junior line that used to be produced. There are larger pieces to snap together than many standard sets, but they are still fully compatible with other Legos.

For example, the bottom of the boat is only two large bricks with only a few more to add on top. In more advanced sets, you may use many bricks to construct the bottom of a boat.

I prefer this method of easier construction to using Duplos. The Duplos won’t work well with regular Legos, though they are somewhat compatible. But when your kids outgrow Duplos, they won’t be very useful. But even when your kid is older, these bigger Lego 4+ pieces can just be part of their Lego brick collection.

For another 4+ set for a Frozen fan, check out LEGO Disney Frozen II Elsa’s Wagon Carriage Adventure 41166 (116 Pieces). Sven is totally adorable!

LEGO City Sky Police Jet Patrol

LEGO City Sky Police Jet Patrol 60206 Building Kit (54 Pieces)

The LEGO City Sky Police Jet Patrol 60206 (54 Pieces) would be a good choice for preschoolers who like police and/or airplanes.

With only 54 pieces, your child can build a cool police plane and a safe for the officer to protect. The cop and robber minifigures will provide lots of fun for your child after the build is complete.

Again, as a 4+ set, this one starts with large bricks for the base to help make the building easier. It looks like the base of the plane is one solid piece.

Parents say this set is quick and easy for a young one to build, even if the parents thought the logistics of arrest would be difficult for a police officer in an airplane. It isn’t big, but as long as you know to expect that, this would be a great first set of Legos for a 4-year-old.

LEGO Toy Story 4 Carnival Thrill Coaster

LEGO | Disney Pixar’s Toy Story 4 Carnival Thrill Coaster 10771 Building Kit (98 Pieces)

Another great movie set is LEGO Toy Story 4 Carnival Thrill Coaster 10771 (98 Pieces). It comes with adorable Buzz Lightyear and alien minifigures.

Your young builder will get to make a roller coaster and track and some theme park touches,  an entrance turnstile, and a food cart with a turkey leg and pizza.

While I think calling a flat circle track a “thrill coaster” is a bit of a stretch, parents say this is an appropriate difficulty level for 4-year-olds. And most people say the simple coaster stays on the track pretty well.

LEGO Toy Story 4 Woody & RC

LEGO | Disney Pixar’s Toy Story 4 Woody & RC 10766 Building Kit (69 Pieces)

My daughter recently got LEGO Toy Story 4 Woody & RC 10766 (69 Pieces) for her 5th birthday.

She did fine building RC herself. In fact, it may have been a bit easy for her, but it would be a great first or early set for a 4-year-old. There are only 69 pieces and many are used to make the obstacles for RC.

She hasn’t seen any of the Toy Story movies yet, so she probably didn’t really appreciate the characters, but I thought it was adorable. The green army men as tiny Lego figures are incredibly cute.

There are many other Toy Story 4 sets in the 4+ group ranging up to 230 pieces:

So if your young one is a Toy Story fan, you can find a set with the right piece count for their experience and attention span.

LEGO City Great Vehicles Garbage Truck

LEGO City Great Vehicles Garbage Truck 60220 Building Kit (90 Pieces)

Next is a wonderful option if your child loves trucks: the LEGO City Great Vehicles Garbage Truck 60220 (90 Pieces)

With the big base pieces in the Lego 4+ line, your 4-year-old or 5-year-old will be able to put this together fairly quickly. Once built, the big waste bin can attach to the garbage truck to dump its load. And then the bed of the truck lifts to deposit the garbage in the dump.

This set also has neat accessories, like some food pieces for trash and some tools for the workers. It is nice to see a male and female minifigure in this set.

We don’t have this exact set, but my son got a Lego Junior garbage truck a few years back. It was fun to build, and he still makes other vehicles on top of the base of the truck.

LEGO Friends Puppy Playground

LEGO Friends Puppy Playground 41396 Starter Building Kit; Best Animal Toy Featuring LEGO Friends Character Mia, New 2020 (57 Pieces)

Next is a fun introduction to the Lego Friends line: LEGO Friends Puppy Playground 41396 (57 Pieces). The bricks in Lego Friends sets are standard Legos, but the minifigures are more lifelike than the classic blocky, yellow guys.

This set has only 57 pieces, so it won’t take too long to build. It comes with one person and two cute puppy figures. Your child will get to build a slide and merry go round for the dogs to play on at the park. There is also a cool skateboard accessory.

You will get the standard visual instructions with this set, but the instructions are also available in Instructions Plus with 3D options if your child gets stuck or just wants to look at the steps differently.

Parents report this set was easy for their young children to build. If your child likes dogs, I think this would be a good choice for an early Lego set.

LEGO Star Wars X Wing Starfighter Trench Run

LEGO Star Wars X Wing Starfighter Trench Run 75235 4+ Building Kit (132 Pieces)

Another cool movie set from the 4+ series is the LEGO Star Wars X Wing Starfighter Trench Run 75235 (132 Pieces).

Your child will get to build a simple X-wing space ship and a laser turret for the stormtrooper to try to shoot it down with. There’s a Luke Skywalker minifigure, plus the stormtrooper and R2D2.

The X-wing’s base is one big piece, making it easy to assemble the rest of the ship. The wings fold flat and out in an X, just like in the movies.

The standalone laser turret is not too faithful to the movie, but I applaud Lego for creating a simple set for the youngest fans. If you have a young Star Wars fan, this will be a great set. I wish it had existed when my son was younger.

Check out our other favorite Star Wars legos!

LEGO City Garage Center

LEGO City Garage Center 60232 Building Kit (234 Pieces)

Another bigger 4+ set is the LEGO City Garage Center 60232 Building Kit (234 Pieces)

Your child will get to build three vehicles and three small structures. The vehicles are a tow truck, sports car, and gas tanker. The cars have one big base piece, which makes the rest very easy to snap together. The tow truck will hook on and pull the sports car.

The structures are a mechanic’s garage, car wash, and gas pump. They each have fun play functions. There are cool accessories like tools and traffic cones.

This set also comes with four minifigures, one for each work station and a driver for the sports car.

Parents really like this set for young kids. It has a higher piece count for a 4+ set, which could tax a child’s attention span to do all at once even if the building is simple.

But since there are six distinct pieces to build between the cars and structures, it could easily be broken into several building sessions. You could start with one car and structure, and your child would be able to take a building break and still have something to play with.

A similar set for 4+ construction fans is the LEGO City Construction Bulldozer 60252 (126 Pieces), which has a bulldozer and wrecking crane.

If none of these seem just right for the 4-year-old in your life, check out our other toy recommendations:

The Best Lego Sets For 5-Year-Olds 

LEGO Classic Creative Suitcase

LEGO Classic Creative Suitcase 10713 Building Kit (213 Pieces)

Another set to let your child be creative with is the LEGO Classic Creative Suitcase 10713 (213 Pieces). This has fewer pieces than the classic bin above, but it has a nice carrying case for Lego play you can bring with you.

This set comes with basic bricks in many sizes and colors and some special pieces like small wheels and eyes. There are several compartments in the case for sorting.

It does come with instructions to build a few small things, but it is great for free play.

I wouldn’t let my kids use it in a plane or car as I think pieces would get lost too easily. But to bring Legos to another destination, this would be great. Some parents have modified the case to add a baseplate to the inside of the lid. That gives kids a great buildable surface right in the case.

LEGO City Space Mars Research Shuttle

LEGO City Space Mars Research Shuttle 60226 Space Shuttle Toy Building Kit with Mars Rover and Astronaut Minifigures, Top STEM Toy for Boys and Girls (273 Pieces)

The LEGO City Space Mars Research Shuttle 60226 (273 pieces)  is a good choice for children interested in space.

It includes a space shuttle, rover with grabber claw, drones, and two astronaut minifigures. The rover has a solar panel and can actually pick up the geode piece to deliver back to the shuttle.

The shuttle is 9 inches long and 8 inches wide, so that’s a decent size. It also has cool details, like a cockpit and a lab for an astronaut to work.

If your child is brand-new to Lego, this might be a bit of a challenge, but parents say it’s great for most 5-year-olds.

My husband has fond memories of the Lego space sets he had as a kid, so he would probably enjoy having this one, too.

LEGO City Pickup & Caravan

LEGO City Pickup & Caravan 60182 Building Kit (344 Pieces)

For camping fans, check out LEGO City Pickup & Caravan 60182 (344 Pieces). It has more than 300 pieces, so it might take a few building sessions for a 5-year-old to complete.

But the end result will be fun to play with. Your child will build a truck and camper trailer that when attached are 12 inches long. The camper can stand on its own as well.

The set also comes with a family of 3 minifigures and some fun camping accessories. You can open a side of the caravan to have the family play in it. The roof comes easily off the bedroom portion (what’s over the truck) to put the figures to bed.

Most builders enjoyed this set as there are a lot of realistic features and play possibilities for a set this size. I think my 5-year-old would like to play with this set, though I imagine she would end up wanting some help with the instructions.

LEGO Friends Juice Truck

LEGO Friends Juice Truck LEGO Truck 41397 Building Kit; Kids Food Truck Featuring LEGO Friends Emma Mini-Doll Figure, New 2020 (103 Pieces)

Next is the LEGO Friends Juice Truck LEGO Truck 41397 (103 Pieces)

While this is also in the 4+ line, I think 5-year-olds would also really enjoy it. It will come together quickly as the base of the truck is one big piece.

Your child will get to build a juice truck and palm tree scene. There are two minifigures, two dolphin figures, and plenty of fruit pieces to pretend to make juice with.

If you look closely, though, there are martini and daiquiri glasses on the menu board of the truck, though they aren’t labeled as such. That does seem a bit strange on a set for young kids. The cup accessories are standard Lego mug and goblet shapes, though.

LEGO City Safari Off-Roader

LEGO City Safari Off-Roader 60267 Off-Road Toy, Cool Toy for Kids, New 2020 (168 Pieces)

LEGO City Safari Off-Roader 60267 (168 Pieces) looks easy enough for a new Lego builder but cool enough that my third grader would enjoy it as well.

In this set, your child will build a cool safari vehicle with space for a minifigure to ride on top to get photos of the animals. There are two explorer minifigures (male and female), a lioness figure, and a parrot figure.

There is also a tree trunk piece that can stand on its own or go on a minifigure’s head as a disguise. 

Be aware that the zebra stripes on the vehicle are all stickers your child will need to place on the pieces. It can be tricky to get them aligned just right. But if you don’t like the stripes, you can just skip the stickers and have a mostly white vehicle.

Parents say this set was fairly easy to put together for young builders, though it will be a step up from the 4+ vehicles. There are more and smaller pieces to fit together.

I think this set would be a great choice for an animal lover. The Lego animals are always a huge hit in my house. Any of my kids would be happy to add the lioness and parrot to their collection!

LEGO City Mail Plane

LEGO City Mail Plane 60250 Pretend-Play Toy, Fun Building Set for Kids, New 2020 (74 Pieces)

If your child loves airplanes, check out LEGO City Mail Plane 60250 (74 Pieces). It is a relatively small, simple set for lots of fun in the sky.

Your child will get to build a small airplane with room for a mail carrier pilot. The propeller spins and the fuselage opens. 

There is also a mailbox so the mail carrier can land and deliver his letters. It also includes a small bird piece.

Parents report their 5-year-olds had no problem building the plane and the set gets played with a lot.

This set is part of the Great Vehicles series of Lego City. Other options are:

LEGO City Burger Bar Fire Rescue

LEGO City Burger Bar Fire Rescue 60214 Building Kit (327 Pieces)

For firefighting fans, there’s the LEGO City Burger Bar Fire Rescue 60214 (327 Pieces).

Your child will get to build a 5-inch-long fire truck and a small restaurant. The fire truck has two storage spaces and a water pump.

The set comes with three minifigures (female and male firefighters and a grill chef) and a motorbike. There are also cool firefighter and restaurant accessories.

When the firefighters arrive at the scene, your child can shoot long Lego cylinders of water at the plastic flames to put the fire out. If your child hits the flames on the restaurant sign with the “water,” the flames topple back.

You do have to be careful that the water pump won’t be aimed at anyone’s face, but it seems like a really cool play feature to simulate putting the fire out.

Parents say it is a nice set with clear instructions and lots of play possibilities. We don’t have this exact set, but we have had a few Lego fire trucks. My son enjoyed them a lot at this age, and it seems like a very classic Lego build. I would recommend this for kids who like firefighters or trucks in general.

If you are looking for a fire truck that’s a bit simpler, try the LEGO City Barbecue Burn Out 60212 (64 Pieces).

The Best Lego Sets For 6-Year-Olds 

LEGO Classic 1500 Piece Set

LEGO Classic 10717 Bricks Bricks Bricks 1500 Piece Set - Encourages Creativity in all Ages - Ideal for Creators of all Ages - Brick Separator Included

To start or quickly grow your child’s Lego collection, LEGO Classic 1500 Piece Set is a great option.

What your child will get in this set is 1,500 Lego bricks of all sizes, shapes, and colors. There are regular rectangular bricks as well as special pieces like wheels, windows, and doors. It also comes with a brick separator tool, which is so useful for getting stubborn bricks apart.

There are instructions included for a few items that are shown on the box, but you have to get some of the others online. I don’t think that’s a big problem for this kind of set, since I think it’s better to let your child build what they can imagine with this one.

Many parents were disappointed with the sizes of the pieces included, though. They thought there were too many small pieces and not enough of the large rectangular bricks good for making buildings.

My kids did get this set from Grandma for Christmas a few years ago. I don’t remember if there seemed to be lots of small pieces, though. They were quickly mixed in with the rest of our Lego collection. It was a good addition to our mess of bricks.

LEGO Creator 3-in-1 Propeller Plane

LEGO Creator 3in1 Propeller Plane 31099 Flying Toy Building Kit, New 2020 (128 Pieces)

Next is an option you can rebuild three different ways: LEGO Creator 3in1 Propeller Plane 31099 (128 Pieces). Being a 3-in-1 set means you can build three different things from the bricks in the kit. But you have to take one model apart to build another. You can’t do all three at once.

The main build is a simple propeller plane. The propeller spins and the wingtips adjust to simulate a real airplane. 

After taking that plane apart, your child can build a helicopter with a landing pad. Finally, the third option is a jet plane that’s pretty detailed considering there are only 128 pieces in the set.

These are small vehicles, only being about 5 inches long. They aren’t meant for minifigures to ride in (though your child could think of unconventional ways to add a pilot). But that keeps them simpler to build.

Parents say their 3-year-old to 7-year-old kids could build this set pretty well and had fun playing with it. If you think your child would prefer a simple plane that a minifigure fits in, though, check out LEGO City Mail Plane 60250

LEGO Jurassic World Dilophosaurus on The Loose

LEGO Jurassic World Dilophosaurus on The Loose 75934 Building Kit (168 Pieces)

For dinosaur fans, I recommend LEGO Jurassic World Dilophosaurus on The Loose 75934 (168 Pieces)

There’s nothing really too big to build in this set. It features a souvenir stand shaped like a dino mouth and a drone with rotors and a working net shooter. There are also 3 minifigures, two with cool Jurassic World shirts. But the coolest part is the Lego dinosaur that’s included. It’s a dilophosaurus with moving jaw.

My son got this set when he was turning 7, I think, and it was pretty simple to put together. Though he’s never seen any of the Jurassic Park or Jurassic World movies, he loves the dinosaurs that come in the sets. He enjoyed building the set, but he didn’t keep it all put together very long. The dino still gets used often in Lego play, though.

This set would be great for any dinosaur fans or kids who are still relatively new to Lego and don’t want a big structure or vehicle to put together.

LEGO Frozen II Elsa’s Jewelry Box Creation

LEGO Disney Frozen II Elsa’s Jewelry Box Creation 41168 Disney Jewelry Box Building Kit with Elsa Mini Doll and Nokk figure for Creative Play (300 Pieces)

The LEGO Frozen II Elsa’s Jewelry Box Creation 41168 (300 pieces) is a good choice for kids who want to make an item to keep and use.

The finished jewelry box is 9 inches high and 5 inches wide. It has a mirror, a drawer, and even a lock. It also comes with two Lego rings.

There are Elsa and Nokk (the horse-shaped water spirit) figures that go on turntables your child can spin. They also can come off the box for play.

Most parents said their 5- to 7-year-old children enjoyed putting this set together and using it. The drawer looks kind of small to hold too much jewelry besides the enclosed rings. But it would certainly look nice on a Frozen fan’s dresser.

I would recommend it for kids who are OK with having something to build mostly for decoration and not for play. If you are looking for a Frozen II set with more play potential, check out LEGO Disney Frozen II Enchanted Treehouse 41164 and LEGO Disney Frozen II Arendelle Castle Village 41167.

LEGO Friends Dolphins Rescue Mission

LEGO Friends Dolphins Rescue Mission 41378 Building Kit with Toy Submarine and Sea Creatures, Fun Sea Life Playset with Kacey and Stephanie Minifigures for Group Play (363 Pieces)

LEGO Friends Dolphins Rescue Mission 41378 (363 pieces) will be a good set for ocean and animal lovers.

Your child will get to build a 5-inch-long submarine and a partial shipwreck that looks pretty cool. The mast on the shipwreck moves to “trap” a dolphin so the explorers included can rescue it with a hook on the submarine.

There are two female minifigures and two dolphin figures. There are also two treasure chests, a smaller personal watercraft, and other ocean accessories like coral and fish. One notable accessory is a treasure map that is revealed when the piece gets wet.

This set looks like it has lots of play value after it is built. The submarine and the shipwreck look really fun, and neither is so big that a 6-year-old couldn’t build it.

Many parents say their early elementary children (girls and boys) love this set. There is a lot to play with, and my kids always get excited about Lego animal figures.

LEGO Creator 3-in-1 Monster Truck Toy

LEGO Creator 3in1 Monster Truck Toy 31101 Cool Building Kit for Kids, New 2020 (163 Pieces)

Though this set is listed for ages 7+, I think most 6-year-olds could tackle LEGO Creator 3in1 Monster Truck Toy 31101 (163 Pieces). The piece count isn’t very high, though there may be some detail work to build the truck up from the base.

This is another 3-in-1 set, meaning the pieces can be built in three different ways. You can’t make all three models at once.

The main build is a monster truck and a small red car for it to drive over. The monster truck isn’t large (3 inches long), but it has cool tires. It also has a working suspension, which is a nice feature on this small of a set.

In the second build, those big tires become part of a finish line for a muscle car to pass under to win the race. The third model is a dragster with big tires in back and small ones up front.

Parents say this is a nice set for younger kids, and the monster truck is a lot of fun to drive over the smaller car. One complaint is that it isn’t meant for a minifigure to ride in. If you want a monster truck with a driver, check out LEGO City Monster Truck 60251 (55 Pieces) or LEGO City Monster Truck 60180 (192 Pieces).

LEGO Friends Heartlake City Hair Salon

LEGO Friends Heartlake City Play Hair Salon Fun Toy 41391 Building Kit, Featuring LEGO Friends Character Emma, New 2020 (235 Pieces)

Another Lego Friends option is the LEGO Friends Heartlake City Hair Salon 41391.

With this set, your child can build the hair salon building and then send minifigures there for a new ‘do. It comes with two minifigures and extra hair pieces, including pink and purple hair.

There are two hairdressing chairs, a sink for hair washing, a nail-painting table, and a mirror. Accessories include scissor and brush pieces as well as a coffee maker.

Parents say this set has nice details and their kids liked building with it and playing with it. It might be a bit of a bummer to not actually be able to style the figures’ hair, like you could with Barbies or similar, but I like that it comes with extra hair pieces to switch out.

I think this set would be good for children who are interested in playing hairstylist.

LEGO City People Pack: Fun Fair

LEGO City People Pack – Fun Fair 60234 Building Kit  (183 Pieces)

Finally, if your child has plenty of building bricks, or just likes playing with the people the most, check out the LEGO City People Pack – Fun Fair 60234 Building Kit (183 Pieces).

This set is mostly minifigures and accessories. It comes with 14 minifigures, plus some carnival games and accessories. There is a cool ice cream bike cart, some food pieces, and a cute rubber duck game.

There is some building to do for the carnival games, but the focus of this set is really the people. It includes kids, adults, and a grandma and grandpa. There’s the ice cream vendor, a guy with a mullet, and my favorite: the stilt walker with an adorable balloon animal Lego piece.

We have enough bricks in our collection that my kids would love an infusion of people like this. Though they are currently bigger fans of the Lego Friends figures than the Lego City figures, I think they would still love to add this many characters to their play.

As long as your child knows this set doesn’t really have much building, this would be a good choice to expand the people in their collection.

If none of these seem just right for your 6-year-old, check out our other toy recommendations:

Buying Criteria for Lego Sets For 4-Year-Olds, 5-Year-Olds, and 6-Year-Olds 

Easy to build

When buying sets for 4-, 5- and 6-year-olds, you want to make sure you don’t get ones that are too complicated until they have good building experience. I have found the age recommendations on the boxes to be pretty accurate for younger kids.

Once your child has had practice and grown in patience and attention to detail, they may be able to tackle sets intended for kids a bit older.

Good for boys and girls

I think any of these sets could appeal to both girls and boys. It’s more important to look at your child’s interests than at their gender.

Lego started the Friends line to appeal to girls, but my son enjoys those sets as well. And my daughters have Lego City sets, too.

Lots of play time

I chose Lego sets that will be fun to build and fun to play with for hours and hours after the build. While some kids do enjoy the building more than the playing after, it’s good to build something with play possibilities.

Good cost per piece

The general guideline I consider when buying Legos for my kids is to spend about 10 cents apiece. So a 200 piece set should be about $20. If you find it for less, that’s a good deal.

I have found movie-branded sets usually go over that by a bit (probably to pay for licensing costs). The sets for 4+ also are a little higher because many pieces are bigger than the standard sets.

Prices can fluctuate quite a bit based on the merchant and if the set is currently in production or retired. My guideline isn’t a hard and fast rule, but it helps me think about if a set is worth the cost.

FAQs About the Best Lego Sets for Kids

At what age can children start using Legos?

Some of my kids started using Legos at age 3. You have to watch carefully with children that young to make sure they don’t put the tiny pieces in their mouths. And they weren’t really following directions to build something specific at that age, but they enjoyed snapping bricks together.

I think four is a great age to introduce Legos. Most kids that age are past putting toys in their mouths, and they can start to follow the simple visual instructions or make their own creations.

But it is never too late to start using Legos! If you have a five or six-year-old (or even older child), they can still start building and have many years of fun with Legos.

What are the benefits of building with Legos?

Besides providing lots of fun for your child, Lego building offers other benefits. Whether they are building their own creations or specific sets, your builders will be honing their spatial relations skills.

Following detailed directions will develop attention to detail and the ability to complete sequential steps. Allowing your child to build whatever they like will let their creativity flourish. Legos can also provide social opportunities to build or play with other children. My kids can play Legos together for hours on end.

As your child advances to more difficult sets, like the Technic line, they can learn engineering and mechanical concepts through the sets they build. In this way, Lego can become a lifelong hobby. That gives it a clear advantage over most kids’ toys.

Which Legos would be good for a 4-year-old?

Lego has a great series of Legos for the newest builders. Look for boxes with a big red circle with 4+ in the bottom left corner. I highlighted several good sets above.

These 4+ sets are standard Lego and compatible with other sets. What makes them different is they have some bigger pieces to start the model off with. This helps building go faster and is easier for small hands.

What are the Lego classic sets?

Classic sets have plenty of Lego bricks, but they aren’t intended to be built into one specific thing. While they have some instructions for things you could make, they are great for allowing builders to use their imaginations.

While building according to instructions is fun and good for kids, the real magic of Legos is taking it all apart and building something new. The classic sets give your builder more pieces to work with on their very own creations.

I recommend the classic sets because great Lego sets for 4-, 5- and 6-year-olds are the ones that get them thinking creatively and building something with their hands.

Final Word

I think the best set to get if you are just starting to buy Legos for 4-Year-Olds, 5-Year-Olds, and 6-year-olds is the LEGO Classic Medium Creative Brick Box 10696. It gives your child a few ideas, but plenty of bricks to use their imaginations with.

The set I recommend for 4-year-olds is LEGO City Great Vehicles Garbage Truck 60220. It will be a quick build, but it has fun play functions as your child can pick up and dump Lego City’s garbage.

For 5-year-olds, I think the LEGO City Safari Off-Roader 60267 is one of the coolest sets this year. It is a bit more complicated to build, but not too challenging. It has some fun people and animal figures as well.

The set I recommend for 6-year-olds is LEGO Friends Dolphins Rescue Mission 41378. The undersea elements are really fun looking. Though Lego markets the Friends line to girls, many parents said their boys love this set as well.
