I enjoy writing these articles for my readers, you guys. I don't accept payment for writing reviews, my opinion on products is my own, but if you find my recommendations helpful and you end up buying something through one of the links I may be able to receive a commission on that. More information

In this age, kids learn about life sciences, how the Earth was formed, how problems are defined, and more.

The science curriculum for 7-8 year olds differs a lot, but these are just a few of the concepts you can expect.

That is why in this article I have collected some of the best STEM challenges for your kids, such as puzzles, robots, but also a rocket!

4 types of STEM toys for 7 and 8 year olds

In math, students learn to use standard units of measure, develop their addition and subtraction to 100, and analyze shapes.

What better way to reinforce what your kids are learning in school than with great educational toys?

If the weather is nice and you feel like experimenting together, I would this 4M water rocket recommend.

Super fun to build your own rocket and 4M has shown that they can come up with great fun educational STEM toys.

Cutest STEM toys 5 and 6 years

Five-year-olds are avid learners and problem solvers.

At this age they learn to count, start adding / subtracting and can tell the time.

This is a time when their enthusiasm for problem solving should be encouraged!

You can help develop their STEM (science, technology, engineering, math) knowledge in a fun way with educational toys for 5 and 6 year olds.

Educational STEM toys for 5 and 6 years

The secret to building STEM skills for beginning learners is to tap into their innate curiosity.

They already develop their engineering and math skills naturally through exploration.

The Boston Children's Museum has this great guide on teaching STEM skills to preschool kids, including simple activities that will encourage them to explore further.

An important point we want to emphasize is that with these activities and toys it is important to build confidence at this age.

Ask "what" questions, instead of "why". This allows the child to feel more like an expert, rather than trying to get to a single “correct” answer.

For example, "What can the magnet pick up?" or "What happened there?" instead of "Why could the magnet only pick up certain things?"

You may not even know some of those why questions!

Asking the “what” questions encourages the child to observe and analyze the situation.

Then they will probably start asking you the 'why' questions so be prepared.

Now let's dive into the best STEM toys for 5- and 6-year-olds!

Makey Makey

Makey Makey

(view more images)

Activities are endless with a Makey Makey. Create your own game or turn a banana into a remote control.

The possibilities are truly endless when it comes to Makey Makey, it can be connected to just about anything as long as it can conduct a little electricity.

You can approach Makey Makey as a scientific laboratory. When using Makey Makey, half the fun is in the planning phase.

You can make the projects as big or small as you want.

Jay Silver has a nice Makey Makey demo:

Some projects can be adapted to take up an entire room, others can be done on a small table.

Here are some ideas to get the creative juices flowing!

The simple circuit

For those kids who are just learning the ins and outs of how electricity works, you can start with a simple circuit project.

Have students create a simple circuit using an LED connected to the Makey Makey board so they know when they have successfully completed the circuit.

You can contribute to this by creating challenges for them. See if they can complete a circuit with people included in the loop, or give them an item to use.

You can add complexity by challenging them to include parallel circuits as well. There really is no limit to this simple project!

To play the piano

This is probably the activity (followed by a viral video) that put the Makey Makey on the map!

To add some music to your playing, you can use the simple piano keys application on the website of Makey Makey here use.

Just plug in the Makey Makey with the USB cable and connect the clamps on the back of the Makey Makey board to just about anything.

You can play with


Bring this timeless arcade game into your home. This project is as simple as you want it to be, free software is available, so you can just download, connect and play.

Or the code can also be changed to add complexity and tailor the game to your kids to make it even more engaging.

You connect the 'moles' you're going to whack to the Makey and this could be anything that conducts electricity (bananas probably won't last that long, so potatoes are a better choice for this).

When the mole comes up on the screen, your child will try to hit it by hitting the potato or other object you have connected.

By changing the code you can essentially change every aspect of the game, and even add pictures of mom or one of the kids as 'moles' to make it even more fun.

No matter how you choose to include Makey Makey in your game, it will certainly open their eyes to the magic of electricity and expand their imaginations.

The games and activities are so much fun that they don't even know they are learning.
