It’s a common joke in the parenting world that the best toy you can give your kid is the box it came in. After all, most of the time that’s what they seem to find most interesting. Perhaps that’s because toddlers are natural-born engineers. They’re curious, unimpeded by the thought of failure and fueled by a “do it myself” attitude. As a parent, it’s your job to keep feeding that fire. And while plain old boxes are great, STEM toys offer limitless opportunity to better understand the world around them and build skills that will carry them (and the rest of us!) into the future.

STEM, which stands for Science, Technology, Engineering and Math, is a new term in the grand scheme of things, but the truth is, there are plenty of ancient toys that fit the bill. Toy blocks, for example are the ultimate STEM toys. They teach kids everything from basic math and physics concepts to problem-solving and hand-eye coordination, all foundational STEM concepts. Perhaps best of all, they can also teach kids to love science.

Incorporating STEM learning toys into your children’s play time can deeply impact their ability to think critically and creatively, and considering more and more jobs and careers depend on STEM-based skills, it’s a worthwhile investment.

The best STEM toys for kids encourage them to get involved and figure something out. They pique their curiosity and invite them to test theories while teaching basics like colors, counting, fine motor skills problem-solving. Whether they’re a toddler who’s just beginning with these concepts or a bigger kid who can apply them to more sophisticated systems like coding, there’s guaranteed to be a STEM toy they’ll love.

TOMY Toomies Squeak Toy, Hide & Squeak Eggs

Tomy Toomies


1. Hide & Squeak Eggs

Once upon a time my 1-year-old and 6-year-old squabbled over these daily. It was annoying, but a true testament to the power of a simple toy. (And their commitment to a lifetime of bickering.) There are tons of different ways to play, from simply taking them apart and putting them back together, matching the inside color to the face, matching the shape on the bottom to fit into the carton and even staging egg hunts. If my experience is any indication, they’ll have a prominent spot on the playroom shelf for an impressive stretch of time. (And inspire sibling arguments for just as long.)

Boon BUNDLE Building Toddler Bath Tub Toy with Pipes, Cogs and Tubes



2. BUNDLE Building Toddler Bath Tub Toy with Pipes, Cogs and Tubes

Bath time with a side of STEM-based play? Yes please. This engaging set of tubes, pipes and spinning cogs will thrill your tot as they experiment with the cause-and-effect action of pouring water through the tubes to watch the spinners start and stop.


Fat Brain Toys


3. InnyBin

Geared toward the littlest learners, this toy provides a frustration-free way to explore shapes and textures. Unlike traditional shape-sorting toys, there’s no right or wrong way to get the shapes inside. Instead, they can push the shapes through the elastic bands then explore and experiment ways to get them back out.

5. The Block Set

If you only ever buy one toy (a girl can dream!) the Lovevery Block Set should be it. The system of 70 wood pieces–all designed to work together to create 20 stage-based STEM challenges and activities–allows kids to experiment with physics concepts like cause and effect, force, magnetism, velocity, and gravity all while simply having fun. Build towers and bridges or work hand-eye coordination by lacing blocks with the wooden dowels and string. Four solid wooden people expand their imaginative horizons as they craft houses and buildings. Bonus: Not only does it all fit neatly into its wooden box, but the box itself converts into a play car!

Ages: 18+ months




6. Dynamo Wooden Domino Set

This brings back a little old school fun: stacking dominos to make a little circuit that you could then knock over in seconds. However, this set is way more advanced that what we used to play with! It includes colorful domino pieces, of course, but it also comes with a bridge, a bell and a ton of tricks for your children to discover.

It helps kids develop spatial thinking abilities, three dimensional thinking and might set them up for a successful engineering career in the future. Also, it’s fun to have timed races!

Ages: 3+




7. 100-Piece Building Set

Arguably one of the most popular toys of the past decade, Magna-Tiles have become ubiquitous for good reason. These colorful blocks are great for encouraging open-ended, creative play and developing math, science, spatial and fine motor skills. The magnetic sides will inspire beginning builders and help more experienced builders think “outside the box.” There are tons of different sets to add on as the obsession grows and don’t be surprised if you find yourself wanting to play with them after the little ones go down for the night!

The flexible and fun Bendy Builders are one of those toys that keep kids of all ages engrossed for hours.

The fun part is just watching as they get in the zone and let their imagination come to life!


Stomp Rocket


3. Stunt Planes

On a dollars to fun ratio, Stomp Rockets may be the best toy investment I ever made. I mean, who doesn’t love the satisfaction of stomping something into space? Kids will spend literally hours setting them up and chasing them down, experimenting throughout the process with direction and force. This particular set includes three different styles of rockets, adding an additional layer of STEM learning as they learn which ones glide, which ones flip and which ones can turn impressive loops. Trust me when I say you’ll be asking for a turn yourself.
