Here at Learning Undefeated, we are always looking for ways to make STEM experiences both easily accessible and fun!

This holiday season our team of professional science educators (who also double as super parents, the cool aunts and uncles, and big siblings) compiled the Top 20 STEM toys under $25. While many of the STEM toys on the market tend to be pricier, we believe that you can play (and learn!) for less. As a trusted resource for teachers for over 20 years working with 50,000+ students per year, we can confidently say we know what kids like!

Our VP of Education, Jennifer Colvin, says it best, “Learning experiences outside the classroom benefit kids’ academic development in so many ways, from building confidence with STEM subjects and nurturing their sense of empowerment, to making connections between theoretical material learned in the classroom with real-world play. STEM toys that are both educational and fun don’t have to break the bank. Our list of STEM toys under $25 provides hands-on learning at a reasonable price point for parents.”
