STEM toys for 7- 9 year olds

For those of you that don’t know, STEM stands for Science, Technology, Engineering, and Math. Any toy that has the STEM tag attached to it is meant to be educational in one of these fields.

STEM toys are a great way to stimulate a child’s mental growth and teach them interesting new things without making them feel as if they are at school.

Because STEM toys are quite plenty, we’ve decided to compile a list of the ones we think are the most fun and educational at the same time.

Note: Deals are subject to change. Keep in mind that the price tag often varies. We recommend going on the vendor’s website to check the price. Some of the products may be out of stock by the time you’ve made your purchasing decision. So, hurry up and hit the buy button.
