These brightly colored blocks are fantastic for toddlers’ STEM development and imaginative play, although small parts may pose a challenge for younger kids.


  • Develops fine motor skills and problem-solving
  • Encourages creativity and color recognition
  • Comes with a convenient storage bag

What immediately caught our attention was the fact that these blocks come with a handy storage bag, making them easy to put away and take along for on-the-go fun.

This feature teaches our child the importance of tidying up after playtime and makes transporting the toy a breeze.

Overall, the Hieoby Montessori Building Blocks are a valuable addition to any toddler’s toy collection, especially for those looking for STEM-focused activities.

5. Hieoby Wooden Tool Set for Kids

Hieoby Wooden Tool Set for Kids

Quick Verdict

This wooden tool set is a fun and engaging option for young kids curious about STEM, but some elements could be improved upon.


  • Encourages STEM and Montessori learning
  • 3-in-1 toolbox design (bench, storage, and carrying box)
  • High-quality solid wooden materials


  • Some pieces are not wooden
  • Difficult to build specific creations
  • Smaller size than expected

Hieoby’s Wooden Tool Set is a fantastic addition to any toddler’s toy collection. The 29-piece set comes with various tools like a hammer, wrench, saw, and screwdriver, allowing little ones to explore and engage in fun construction play.

One aspect I like is that this toy encourages both STEM and Montessori learning.

Kids can improve their fine motor skills, hand-eye coordination, and problem-solving abilities while playing with the colorful wooden tools. It’s great for children aged 2 to 6, making it a versatile and engaging option.

The 3-in-1 toolbox design adds to the toy’s charm and practicality.

The box can be flipped over to serve as a workbench, encouraging role-playing and enhancing the child’s experience. Adding the handle turns it into a carrying case, making transportation a breeze.

When playtime is over, the toolbox acts as storage, promoting tidiness and organization.

However, we noticed that not all pieces in the set are wooden.

This detracts from the overall aesthetic and durability the wooden components offer. In addition, it’s not easy to build specific creations with the available pieces, which might limit a child’s imagination during playtime.

The size of the set is also smaller than we initially assumed, making it a less-than-impressive gift upon first glance.

Despite its drawbacks, the Hieoby Wooden Tool Set remains an enjoyable and educational toy for young children interested in construction and STEM-based play.

6. USATDD Counting Animal Matching Games

USATDD Counting Animal Matching Games

Quick Verdict

The USATDD Counting Animal Matching Games set is the ideal choice for parents and educators looking to help toddlers develop essential STEM skills in a fun and engaging way.


  • Entertaining and education-focused
  • Durable and washable rubber material
  • Suitable for a wide age range (3-6 years)

  • Tweezers may be challenging for some toddlers
  • Limited in complexity for older children

One thing we should mention is that the animals in this set are a bit small, which could be a concern for younger children. However, this can also serve to help them enhance their fine motor skills and hand-eye coordination. Tweezers can be challenging for some toddlers, but they are great for developing fine motor skills in those who are ready for this activity.

One small issue we noticed is that, while it is suitable for a wide age range, older children might find the activities too simplistic. However, we would still recommend the USATDD Counting Animal Matching Games as one of the best STEM toys for toddlers.

  • High-quality and safe materials
  • Encourages creativity and spatial awareness
  • Suitable for a wide range of ages
  • Unique spin on popular magnetic toys


  • Larger size might make storage a challenge
  • Might not be as durable as other similar toys

I love the bright colors and building possibilities offered by the 48 blocks included in this STEM skills set.

Safety-wise, the larger size of the blocks mean that accidental swallowing shouldn’t be an issue and the ABS material is sturdy.

These toys help toddlers develop a sense of space, as they can effortlessly transition from creating 2D to 3D structures.

The BigShu Magnetic Blocks are ideal for parent-child bonding time or even just a solo play session for your little one.

I noticed that some of the stones were smaller than expected. This might create a slight challenge for some toddlers when trying to grasp and stack them. Also, the age recommendation on the packaging is inconsistent, stating both “suitable for 1 year and up” and “not for children under 3 years.” This discrepancy is worth considering when selecting a toy for younger children.

Though the blocks had plenty of pros, we did notice a few potential downsides. For one, they seemed smaller than they appeared in the product images. Also, the set comes with only 28 blocks, so it would be great if there were more included for added variety.

Lastly, a few different shapes other than cubes would undoubtedly enhance the building possibilities and help with further toddler brain development.

While they may not be perfect in every aspect, the pros definitely outweigh the cons. Give these blocks a try, and watch as your little ones unleash their boundless imagination!

Buying Guide

STEM educational toys are designed to spark curiosity, foster creativity, and enhance problem-solving skills in young minds.

But as we explore the world of STEM toys for toddlers, there are many factors to consider when choosing the best product for your little one. Let’s dive into the features and elements to look for in a perfect STEM toy.

STEM Toy Buying Guide

Age Appropriateness

First and foremost, always look for age-appropriate toys. STEM toys typically indicate a recommended age range, which will ensure the toy is safe and engaging for your toddler. Keep in mind that age recommendations can also serve as a guideline for skill level.

Educational Value

When selecting a STEM toy, consider its educational value. The best toys will teach your child about science, technology, engineering, or mathematics concepts while fostering a love for learning. Look for toys that encourage critical thinking, problem-solving, and creativity.

Durability and Safety

As we all know, toddlers can be quite rough with their toys. When searching for the perfect STEM toy, ensure it is made from high-quality, non-toxic materials that can withstand the wear and tear of everyday play. Additionally, the toy should not have any small parts that could pose a choking hazard.

Interactive and Engaging

A great STEM toy for toddlers should be interactive and engaging, holding their attention for extended periods. Toys that involve building, experimenting, or using their imagination are typically more engaging than those that only promote passive play.

Adaptability and Growth

Finally, consider the toy’s adaptability and potential for growth as your toddler’s skills develop. The best STEM toys can be enjoyed in different ways, offering a higher level of complexity or customization as your child learns and grows. This will ensure that the toy remains relevant and valuable over time.
