Buyer’s Guide

Before you shop for STEM toys for a four-year-old, here are some factors to consider.

Manual vs. Tech-Based

As you can see from our reviews, some of these STEM toys are manual in nature, whereas others are technological. In other words, do you want something that will train your child’s hands more than the brain, or vice versa?

For example, manual building games also target cognition but focus more on manual dexterity. On the other hand, technology-based games are more oriented towards cognitive thought.

The Type of Learning

Related to the above point, what do you want these games to teach your children? Some deal with letters, numbers, colors, and shapes; some are for building, coding, and more. You want to focus on the game’s design to help your child develop.


Also, pay attention to safety aspects, especially with manual building games. Finally, ensure that all components are made of child-friendly materials. This means that they should be nontoxic and preferably not have sharp edges.

The Age Range

This article reviewed STEM games for four-year-olds. However, every child is different. For example, you might have a brilliant 3-year-old or a slightly slower 5-year-old. The point is that you have to judge which games are best for your child based on their level of development.


If you get a manual game with various physical components, make sure they are durable. Children are usually not that careful with their belongings. Durability is therefore essential.


How Old Does a Child Have to Be to Play a STEM game?

These educational toys and games are designed for children as young as one-year-old. You just have to get the appropriate game based on your child’s age.

What Skills Do STEM Games Help Develop?

STEM games are ideal for developing various skills, including basic cognition, memory, problem-solving, logical thought, spatial awareness, pattern recognition, manual dexterity, hand-eye coordination, and more.

Do All STEM Games Require Computer Skills?

No. However, some games, such as coding games, do require basic computer skills. If your child is not familiar with a computer, you can start teaching them these basics at an early age.

Are These Toys Good for Both Boys and Girls?

Yes. While boys and girls may have different preferences in toys, there is no scientific evidence that suggests that one type of toy is better for a particular gender.

What’s the Best Way to Teach My Child With These Games?

The best way to teach your child is to let them play. That said, you can also join in and play with them to help them understand the game better. You can also use these games as a bonding experience between you and your child.


We think the best STEM toy for a four-year-old is the SNAEN Science Kit STEM Toy. This might be a personal bias, but do you remember how much fun you had playing with science kits as a child? That said, all five of the educational STEM toys reviewed today are ideal in their own ways.
