35 Best STEM Toys for 2-Year-Olds in 2024

Last Updated:

The best STEM (science, technology, engineering, and math) toys for 2-year-olds are educational and can help your toddler reach important developmental milestones.

The best part? My toddlers have no idea they’re learning because playing with STEM toys is so much fun.

If you’re ready to keep your toddler engaged and teach important skills at the same time, read on to learn about the 35 best STEM toys for 2-year-olds.

Most of these are also open-ended, which is just the cherry on top.

What Are STEM Toys?

STEM stands for science, technology, engineering, and math. According to Southern Illinois University, STEM toys provide “hands-on, problem-based learning.”

A toy that falls under the STEM category doesn’t have to address all four categories, either.

Here’s what the Administration for Children & Families says about STEM learning for toddlers:

“STEM can refer to the subjects individually or one or more working together, but can also mean a way of doing things that includes solving problems, asking questions, and exploring the world around us.”

Your toddler will start to understand concepts and build on skills that support getting ready for a school setting.

Plus, it’s such a good feeling knowing that when your 2-year-old is stacking blocks, they’re actually soaking up so much education!

Toys in the STEM category can introduce kids to early science concepts, such as engineering, hypothesis forming, and hands-on learning.

Other toys highlight technological concepts like coding and challenging kids to think sequentially to solve problems.

Toys that encourage number, shape, and pattern recognition offer introductory math skills that kids can use to solve problems.

Ultimately, the goal of STEM toys is to bridge play with learning.

“Play is the work of the child.”

–Maria Montessori

STEM Toys for 2-Year-Olds Shopping Tips

Before you start shopping for the best STEM toys for your 2-year-old, here are a few things to think about:

  • Your child’s interests: with so many STEM toy options available, you can choose one that suits your child’s interests, whether they love to build and create, read, or solve puzzles.
  • Skill development: perhaps your toddler is great at color recognition but could use some help with numbers. Choose STEM toys that meet their current educational needs to develop the necessary skills for preschool and beyond.
  • Toy construction: if choosing eco-friendly toys is important to you, you can find many toys on this list that use recyclable, renewable, and child-safe constructions.

The bottom line is you don’t need all 25 of the toys in this guide, so hopefully, these tips will help you pick and choose which STEM toys are best for your little one.

And the ones you don’t buy straight away? Add them to your Christmas wishlist so your family gets you toys you actually want in your home. 😉

Top STEM Toys for 2-Year-Olds

Explore this list of STEM toys for 2-year-olds to give your toy collection an update with educational options that your child will enjoy.

1. The Investigator Play Kit

Lovevery Amazon Alternatives The Investigator Play Kit for Months 31, 32, and 33

Price: $120

The Investigator play kit from Lovevery was developed for months 31-33, and it has some incredible toys in it.

The Liquid Lab is an obvious stand-out when thinking about STEM, but all of these toys have great educational benefits.

This play kit supports natural curiosity, problem-solving, and critical thinking.

I remember watching my daughter’s gears spin when trying out the Twist & Pivot Pattern Puzzle for the first time. It’s really something to watch!

Children using Lovevery educational toys

If you want to gift STEM-friendly toys that have a ton of other educational and developmental benefits, this would be my top recommendation.

2. Water and Sand Sensory Table

kiwico water and sand sensory table for early stem activities

Price: $179.95

This sensory play table from KiwiCo comes ready for all kinds of splashy, sandy, creative fun. It’s perfect for early STEM activities!

Kids can create custom water features with the pipe set, explore art with the paint crayons, or dig into a sand bin.

The height is adjustable so it’ll grow with your child, from toddler to big kid.

Most water tables on the market are plastic, so I really appreciated that this one was made of wood.

3. Thomas & Friends Wooden Track Set

thomas the train

Price: $53.99

Another STEM toy we absolutely love in our house is wooden train tracks. We have a mashup of different brands at this point (most will fit together), but the highest quality ones we have are hands-down Thomas & Friends.

If you’re on a budget or want a higher volume of tracks for the price, the next best would be BRIO (in my opinion). Both brands fit together, so you can have both (we do).

Here are a few product recs:

Note: Make sure to get the wooden tracks and not the plastic ones!

jack playing with the train table

A box of train tracks, a few accessories, and a few trains will keep your 2-year-old busy for hours. It’s also kind of fun for parents and grandparents, too.

Figuring out how to design a train track that closes up neatly is a challenge, and 2-year-olds love it when their family gets on their level and plays with them!

This hands-on toy is sure to challenge your child’s imagination and creativity and help them build their fine motor skills as they move the engine around the track.

4. Roll ‘n Go Wooden Marble Run

Roll 'n Go Wooden Marble Run

Price: $54.95

The high-quality, solid wood construction makes for a long-lasting toy that’s fun and looks good.

Your toddlers can experiment with a marble run that doesn’t have tiny, dangerous pieces. Marble runs are fantastic for STEM learning as it involves creativity, problem-solving, critical thinking, and hand-eye coordination.

5. Connetix

Connetix packaging

Price: $115

Magnetic tiles allow toddlers (and parents, let’s be honest) to use their imaginations to build castles, buildings, vehicles, and so much more while considering spatial and engineering concepts.

Magnetic tiles are quite possibly one of our favorite toys of all time. Connetix is the best brand (I tested 14 different magnetic tiles and blocks) as the magnets are strong and the construction is safe and durable.

Kids can also practice their hand-eye coordination and dexterity as they fit the magnetic tiles together. This is also a great investment if you plan to have multiple kids.

My 11-month-old loves playing with these, and my 4.5-year-old does, too. This is one of those toys that will be a staple in your house for years.

6. Connetix Ball Run

As long as we’re talking about magnetic tiles, I have to mention the Connetix ball run.

connetix sams club ball run pack

Price: $109

The Connetix ball run comes with clear tubing, and it’s the ultimate STEM toy. It introduces so many different concepts, particularly engineering, as your toddler or child can experiment with different layouts.

At age 2, you’ll need to help a bit, but my almost 2-year-old absolutely loves dropping the wooden balls down the ball runs I make with my older kiddos.

The balls are much larger than magnets, so you don’t have to worry so much about choking hazards.

7. Lovevery Block Set

lovevery block set

Price: $90

A brilliant, practical system of solid wood blocks for building spatial, language, and problem-solving skills. Crafted by child development experts, these wooden toy blocks offer years of learning through play.

Our kids absolutely love the Lovevery Block Set.

Jack using shape sorter part of lovevery block set

We finally just put it in the closet for a break in our toy rotation, but I’m telling you, those have been firmly on our toy shelf since we bought them in May of 2021.

I’ve written a post about 10 reasons why the Lovevery Block Set is worth the price, but here’s the gist: it fosters so much creativity, exploration, and learning.

It was made by child development experts and allows kids to categorize, stack, roll, and connect the blocks in many ways (you can even use the wooden storage box to turn the thing into a pull car!).

The age-based activity guide also shows you how to make the most of the set and offers learning opportunities for your 2-year-old.

The set includes a cookie jar with 11 cookies that have the numbers 0-10 printed on the bottom and the corresponding number of counting chips on top.

It’s a great way to introduce early counting and math concepts to a 2-year-old.

10. Window Bird Feeder

window bird feeder

Price: $27.95

Toddlers get a kick out of seeing animals, so why not bring them to the window?

Bird feeders are an awesome opportunity to observe nature with your toddler. Life is so busy these days – take a moment to slow down and appreciate the beauty.

You can also buy a bird species book and try to identify bird species with your little one. You’ll probably learn a thing or two along the way!

It’s likely best to buy a bird species book that corresponds with where you live. This one from National Geographic covers North America, but you can also buy books specific to your state.

11. Blockaroo Blocks


Price: $129.99

If you’re looking for a STEM toy for bath time, Blockaroo Blocks are it! These foam magnetic blocks click together, float, and stick to the side of the tub.

My kids are obsessed with these, and I have three that span from ages 11 months to 5 years old. This is a STEM toy that’ll last a whole lot longer than just age 2!

Not only are these foam shapes fun to play with, but they allow your toddler to learn about colors and shapes as they bathe.

Kids can stack them in a variety of designs, challenging their creative thinking and building abilities. Good news for parents: These blocks are dishwasher-safe, allowing you to clean them with ease.

12. Enthusiast Play Kit

enthusiast play kit

Price: $120

This Play Kit includes opportunities for your child to refine their motor precision, explore geometry, and experiment with weight and balance. The tea set in this one was our kid’s favorite toy!

The balancing scales in this kit are definitely the most “STEM-focused” as you can introduce early concepts of balance and measurement.

13. Computer Engineering for Babies Book

computer engineering for babies

Price: $33

A showstopper STEM toy that focuses on technology is the Computer Engineering for Babies book. This book actually teaches babies and toddlers the principles of coding.

With two buttons and an LED, the book explores basic computer logic gates, including NOT, OR, AND, XOR, and a Latch. The book uses light sensors to detect which page is open and change the operands accordingly.

Who would’ve thought you could reasonably expose your toddler to this type of tech in a way they can truly absorb?!

Hats off to this small business! I reached out, and they provided me and my readers with code TWOMAMABEARS for 10% off. Doesn’t get better than that.

14. Melissa & Doug Take-Along Wooden Tool Kit

melissa and doug take along wooden construction set

Price: $9.99

This sturdy wooden pretend play set helps toddlers develop hand-eye coordination and problem-solving skills while also teaching them about counting, sorting, and color recognition.

My son always wanted to do what daddy was doing, so a toddler-friendly toolset was always a staple in our home.

It’s a great toy for engineering and math concepts, and while it’s primarily recommended for ages 3-5, age 2 is when our son was the most interested in toys like this one.

15. Blippi My First Science Kit with Color Experiments

blippi my first science kit

Price: $17.18

Blippi is here to help you teach your toddler about primary and secondary colors in a fun way with this all-inclusive science lab kit. My toddlers are obsessed with color mixing, and if yours love Blippi, they’ll be even more excited about it.

I love books like these that make it approachable.

17. Lovevery Drip Drop Cups

Lovevery drip drop cups

Price: $20.99

The Drip Drop Cups are one of our most-used and loved Lovevery toys. They are constantly in our toy rotation because they provide so many ways to play.

Lovevery sells some of their standalone toys at Target, which is super convenient if you don’t want to subscribe to the full-blown play kits.

You can use these stacking cups in the bathtub, you can stack them, nest them, pour from one to the other, do some color sorting with objects inside the cups… the possibilities are endless.

When stacking, your 2-year-old can develop balance and logic skills. Nesting, pouring, and containing the water in the cups lets kids learn about sizes, shapes, and what fits into what.

18. Melissa & Doug Lace and Trace Activity Set

Melissa & Doug Lace and Trace Activity Set

Price: $9.09

Challenge your toddler’s dexterity and build their fine motor skills with these lacing cards from Melissa & Doug.

Your two-year-old can practice weaving the laces through the holes, which can also boost their hand-eye coordination.

This is a particularly great toy to have during car rides, church services, or other times when you just need your little one to be occupied for a bit.

19. Monster Math Scale

hape monster math scale

Price: $23.99

The Hape Monster Math Scale toy offers plenty of STEM-based learning and fun. The monster weights are numbered, helping with number identification and forming and solving simple equations.

Kids can use their reasoning skills to determine which monster weighs more and then test their hypothesis using the scale. This toy comes with a convenient storage bag, offering easy clean-up that I certainly appreciate.

Hape brand toys are generally of a higher quality – if this particular toy doesn’t seem right for you, I’d definitely browse their other toys. They have some really good ones!

20. Boynton’s Greatest Hits The Big Blue Box (Boxed Set)

boyntons greatest hits book box set

Price: $16.79

Boynton’s books are not only my kid’s favorites (you can’t beat the rhymes!), but there are always beginner math lessons tucked inside.

Some of her very best books are in this box set:

  1. Moo, Baa, La La La!
  2. A to Z
  3. Doggies
  4. Blue Hat, Green Hat

One of my favorites of all time is Blue Hat, Green Hat, which has all kinds of educational concepts hidden inside.

We have color recognition (what color is this shirt?), counting (how many shirts are on this page?), and size comparisons (which shirt is bigger? which is smaller?).

21. Guidecraft Stacking Transparent Rainbow Pyramid Set

Guidecraft Stacking Transparent Rainbow Pyramid Set - 6 Pieces

Price: $39.95

With hardwood frames and vibrant, transparent acrylic windows in primary colors, these blocks invite exploration and learning for children aged 2 and up.

Price: $13.59

Told in minimal, playful text, this story shows readers that even the biggest “mistakes” can be the source of the brightest ideas—and that, at the end of the day, we are all works in progress, too.

As one artist incorporates accidental splotches, spots, and misshapen things into her art, she transforms her piece in quirky and unexpected ways, taking readers on a journey through her process.

I love finding STEM learning opportuities in books, and this one is no exception. Lines like, “One eye was bigger than the other. That was a mistake.” introduce size comparison concepts.

I’ll let you discover all the other learning opportunities here, but at the end of the story, the story and message is absolutely stunning.

24. Learning Resources Smart Snacks Number Pops

Learning Resources Smart Snacks Number Pops

It doesn’t get the kids’ hands messy, and it’s totally open-ended, allowing kids to get creative with imaginative play.
