Top STEM Toys that Foster Cognitive Development

Share This!

Here they are! Our current top picks for STEM toys that we’ve enjoyed over the years for fostering cognitive development in children. This list is great for children of nearly all ages from 3-18 years. I took the liberty of dividing the list into two sections; For Big Kids and For Little Kids. Many of these toys are award-winning, top-rated, and highly affordable. Not one brand is sponsored and all opinions are my own (and my kids, of course).

What is Cognitive Development?

To put it simply, Cognitive development means how children think, explore and figure things out. It is the development of knowledge, skills, problem-solving, and dispositions, which help children to think about and understand the world around them. Brain development is part of cognitive development and there are many things parents, teachers, and caregivers can do to help foster cognitive development in children. Reading books is perhaps one of the best ways. Playing with STEM toys is another great way to challenge your child’s mind and nurture their brain.

Why Are STEM Toys Important?

STEM toys prompt children to think critically and explore different ways of solving problems. Both of these components are essential for fostering cognitive development, especially the left side of the brain that helps children develop the full scope of language. STEM toys also spark the imagination and encourage creativity, activating the right side of the brain that helps children pay attention, stay focused, and monitor mistakes.

For Big Kids and Teens

1. LEGO Boost Robot Building Set and Educational Coding Kit

LEGO Boost is an award-winning toy and so much fun. The set includes 847 LEGO pieces that kids can build and rebuild into 5 cool multifunctional models. My little scholars built Vernie the Robot and enjoyed programming the robot to dance and tell jokes. You do need a smartphone or tablet to download the free app, which is what your children will use to code and program their constructed models. Best suitable for ages 7-12 years

2. Robotics Pick and Drop Machine

This STEM-based construction kit explores kinetic motion. It works by spinning the crank to transfer energy through the arm linkages, which activates three grabber hands that reach down and grab a ball and then release them onto the return ramp. This model is a challenge to build but so much fun to play with when completed. There are no batteries required to enjoy this kit. Most suitable for ages 8-15 years.

3. LEGO Architecture New York City Skyline Model Kit

LEGO Architecture sets come in many models. We’ve personally enjoyed three of the many sets the brand has to offer. The New York architecture set includes the Statue of Liberty, Flatiron Building, Chrysler Building, Empire State Building, and the One World Trade Center. It is a great addition to a lesson on the history of New York’s famous skyline buildings, or just for fun. Although the recommended age is 12-15 years, my architecture enthusiast was able to build these models as young as eight years old.

4. KEVA Maple 200 Plank Set

KEVA planks are great for practicing balance, leverage, geometry, and the principles of physics. They are tough, durable, and come with endless creative possibilities for all ages. The set includes an idea book and step-by-step instructions, or kids can build from their imagination. My boys loved building tall skyscrapers and elaborate structures with this kit. I do forewarn that smaller children may get frustrated as balance is truly a necessary skill when playing with these planks.

5. Makey Makey Invention Kit for Educational Engineering and Computer Coding

This science kit is great for non-tech savvy children and teens. There is no requirement for programming knowledge or cumbersome software installation. Just plug it up, clip, and play! There are many cool things you can do with this kit, like work with circuits, make a banana piano, and play with musical water. Our favorite creation, however, was our roast beef sandwich computer mouse. No, you did not misread; it was an actual roast beef sandwich we were able to use to control the computer. It was awesome! Suitable for ages 8 and up.

13. Kids Fort Building Kit 

If there was one STEM toy that stood the test of time, it was this fort set. My kids would honestly still build with this set if we weren’t missing pieces. They’ve enjoyed it for about five years. The kit comes with 120 pieces, but I recommend buying two so that your kids can build really huge forts! This activity encourages kids to work together to plan, solve problems, and construct different creative structures. You’ll need lots of old sheets to cover the structures. They are so durable that we’ve even homeschooled in these. Great for ages 5 and up.
