Best STEM Toys

Verywell Family / Lecia Landis

STEM is an acronym for Science, Technology, Engineering, and Math, four important and correlating areas of study. Over the years, educators have put more and more emphasis on STEM, and younger kids can get an early introduction to it through play. If your kiddo's favorite subjects revolve around math and science or they have dreams of becoming a video game creator one day, then sprinkling in a few STEM-related toys into their collection can help mold those interests.

According to Allison Tsomos, vice president of operations at Celebree School, “STEM objectives include teaching skills to solve problems, learning to gather information, and developing deductive reasoning through evaluating evidence to make decisions. STEM is most often introduced to students through guided investigations and hands-on learning opportunities." STEM toys will incorporate learning science, technology, engineering, and math concepts into age-appropriate play.

Creating fun ways for children to engage with STEM learning through play allows them to connect learned concepts to real-world applications. In addition to being educational, the best STEM toys are also just fun for kids to play with and can be quite entertaining and encourage problem-solving, teamwork, and critical thinking. After speaking with experts like Tsomos, we carefully considered toy safety, age recommendations, design, ease of use, and value when reviewing products.

Here are the best STEM toys for kids that tick all of the boxes. 

Osmo Genius Starter Kit for iPad

Osmo - Genius Starter Kit for iPad - 5 Educational Learning Games - Ages 6-10 - Math, Spelling, Creativity & More - STEM Toy Gifts for Kids, Boy & Girl - Ages 6 7 8 9 10 (iPad Base Included)


  • Five games

  • Beginner- and expert-friendly

  • No Wi-Fi necessary for games

  • "Monster bundle" more costly

  • iPad required

  • Too complicated for some kiddos

The Osmo Genius Starter Kit ranks high on our list because this bundle includes five games in which kids use physical pieces to interact with their tablet screen, learning math, marine biology. The set comes with a mirror and stand which turn their iPad into a way to interact with included pieces and kids can move around on a tablet.

If five games aren’t enough for your child, there are options to increase to seven or opt for the “monster bundle” which includes more games and accessories. For younger kids, the Little Genius Starter Kit is designed for preschoolers and offers similar games and accessories. One important thing to note is that this kit comes with everything your child needs to play the games except for an iPad, which is required.

What Our Testers Say

"Our kids tinkered away for an hour straight after we opened the box, then later requested even more playtime—and there was plenty to do! Because kids can create their own designs after they’ve gone through all of the experiments, there’s more to do beyond the pages of the manual, which adds a lot of value to this kit."—Sarah Wassner Flynn, Product Tester

How We Selected the Best STEM Toys for Kids

We chose the best STEM toys for kids by researching reviews from customers and competitors, and studying the features of more than 50 products on the market. We considered age recommendations, design, size, features, ease of use, and value when deciding our picks. We also consulted with Allison Tsomos, vice president of operations at Celebree School, for any considerations or product recommendations while reviewing guidance from the American Academy of Pediatrics on toy buying safety.

What to Look For When Buying STEM Toys

Type of STEM Toy

There is no shortage of great STEM toys that fall into multiple categories, which is great for kids with a general interest in all things science, technology, engineering, and math. However, some kids will have more individualized interests so it’s worth taking the time to ensure you’re getting the right toy for your child. “There are [...] toys that are crafted for a particular skill development, like coding,” says Tsomos, “so consider your child’s current interest or one you want to introduce [when buying a toy].” 

Breaking Down STEM

According to the Boston Children’s Museum, each STEM category is broken down like this:

"Science is a way of thinking: Science is observing and experimenting, making predictions, sharing discoveries, asking questions, and wondering how things work."

"Technology is a way of doing: Technology is using tools, being inventive, identifying problems, and making things work."

"Engineering is a way of doing: Engineering is solving problems, using a variety of materials, designing and creating, and building things that work."

"Math is a way of measuring: Math is sequencing (1, 2, 3, 4…), patterning (1, 2, 1, 2, 1, 2…), and exploring shapes (triangle, square, circle), volume (holds more or less), and size (bigger, less than)."

Age Appropriateness

As with any toy, it’s important to ensure the STEM toy you get for your child is appropriate for their age and skill set. “STEM toys are specifically designed for certain developmental milestones based on typically developing children,” Tsomos notes, “so be attentive to the target age range [when shopping].”

The easiest way to do this is by following the manufacturer’s recommended age range on a toy’s box, but you can also take a look at the toy/activity itself and assess whether or not your child has the skills needed to play with it successfully. Things to consider include whether or not your child can read, count, identify different colors and shapes, and/or has the necessary motor skill development (particularly fine motor skills). 

Entertainment Value

Of course, if you want your child to actually play with a STEM toy, it needs to be fun, otherwise, it will sit on a shelf collecting dust. First, as previously mentioned, make sure it falls into a STEM category that your child genuinely enjoys, and then consider the other types of toys they tend to be drawn toward and use that as a guide.

Tsomos notes that shoppers shouldn’t “get caught up in the marketing of STEM toys” because a lot of toys can fall into one of the categories, even if they are not labeled as such. Instead, she recommends “think[ing] about what your child will have fun with and what will positively challenge [them].” She also suggests considering toys that you can play with or engage in with them. She says, “The expanded value of STEM toys comes from the curiosity of the child or [from] a parent or teacher prompting fun questions or challenges” while they’re playing with the toy.

Frequently Asked Questions

  • Why is STEM important?

    Allison Tsomos, vice president of operations at Celebree School explains to Verywell Family that an emphasis has been placed on these subjects because research has shown a deficit in knowledge in these areas over the last 20 years, so educators are introducing concepts as early as preschool “with the hopes to spark secondary and collegiate studies in these subjects." According to Best College Reviews, some great careers that fall under the STEM umbrella include environmental engineer, statistician, software developer, actuary, computer and information research scientist, biochemist, medical engineer, geoscientist, accountant, and web developer. 

  • What is the difference between STEM and STEAM?

    Like STEM, STEAM is an acronym that includes Science, Technology, Engineering, and Math, but with the addition of “A”, which represents Arts. “The addition of the Arts encourages learners to look at things with a more innovative and creative lens,” explains Tsomos. “There is more inquiry-based learning, opportunities for communication and collaboration are encouraged, and cultural influences enrich the STEAM-based curriculum.” Additionally, she says that by adding Arts to the mix, it allows students to use both sides of their brain when studying. “When STEAM is appropriately incorporated into a learning environment, all students will be engaged and cross hemisphere learning will result.”

Why Trust Verywell Family

This article was written by Ashley Ziegler, a full-time parenting writer, and a mom to a 2-year-old and 5-year-old. Over the years, she has researched and tested hundreds of children’s products for both her writing career as well as for personal use as a parent.

As her oldest daughter approaches kindergarten, Ashley has put a lot of emphasis in finding toys with an educational component, including both STEM and STEAM toys. When creating this list of recommendations, she considered her personal experience with STEM toys/games, the insights of an early childhood education expert, as well as products’ quality, longevity, age-appropriateness, and safety.
