It comes with a bin of almost 500 pieces in varying colors and sizes, allowing your child to use their imagination and get creative.

  • 3. LEGO Creator 3in1 Monster Truck Toy

    (Most versatile — $)

    Why it’s great: It can be frustrating spending a ton of money on a LEGO set that only allows you to build one specific design. The LEGO Creator sets have eliminated that issue. These sets allow your child to use the same pieces to build three different designs, all different vehicles, offering plenty of versatility and hours of fun. The main build is a cool Monster Truck. And, of course, you can build a smaller car for your truck to drive over. While the set is recommended for ages 7+, it’s easy enough for kids a year or two younger to put together.

    Keep in mind: You can’t build all three designs at the same time. Instead, you’ll use the same pieces to build each.

    Good for: Kids who want to be able to build a few different designs with one LEGO set.

FAQs about LEGOs for 6-Year-Olds

  • 1. What are the benefits of playing with LEGO sets?

    LEGOs are a ton of fun, which means they’ll likely keep your little one occupied for hours. Beyond that, they offer a whole host of other benefits. For one, they increase hand-eye coordination, fine motor skills, and spatial relation skills. They also inspire creativity and imagination. More difficult sets offer even more benefits, increasing STEM skills and mechanical and technological skills. Plus, kids can build together, so LEGOs can also help build social and language skills.

  • 2. At what age can my child play with LEGO sets?

    There are LEGO sets designed for kids as young as three or four, but these sets are usually Duplo sets, which have much bigger bricks and pieces for safety reasons. As your child gets older, the sets come with smaller bricks. Around five is when kids generally start using the typical LEGO bricks that you’re probably the most familiar with. Sets get more complex and come with more parts as the age recommendation gets higher, and there are sets, like the Technic sets, that also incorporate more mechanical engineering concepts.

  • 3. What are LEGO Classic sets?

    LEGO classic sets come with tons of bricks, but they don’t come with instructions to build any specific item. These are great when you’re just looking to add in extra bricks to allow your child to use their imagination and build whatever they want. They’re great for boosting creativity, as your child will have to think and design their own buildings or creations.

  • 4. Are LEGO sets a good STEM toy?

    Definitely! Every LEGO set out there uses engineering skills. Your child will also be using skills like critical thinking, problem-solving, and quite a few more when building these sets. Math and science are also used when you’re child is counting pieces or using force and motion to fit pieces together and play with the designs.

  • 5. What features should I look for in a LEGO set for 6-year-olds?

    There are different types of LEGO sets for different ages, so the first thing you’ll want to do is make sure the set you get is age appropriate. After that, it’s all about personal preference. Find a set that aligns with your child’s interests. Are they a Marvel, Jurassic World, or Super Mario fan? There are LEGO sets for that! Do they love cars, planes, or any other type of vehicle? LEGO has plenty of those! No matter where your child’s interests lie, there’s a good chance you’ll find a LEGO set designed around that theme.

Conclusion

LEGO sets have been popular for years, and they’re one toy that you’ll never regret buying. They’re durable, fun, and help your child improve tons of different skills. These little bricks are versatile, allowing your child to use their imagination and get creative. Providing hours of fun for little builders, you can’t beat these toys.
