What We Do

Engaging Contests

Download our activities to conduct with your students and upload the results to compare your class’s scores to the scores of classes from all over the country.

Aligned Content

Our activities include pertinent supplemental curriculum material that is aligned to National Standards.

Emphasis on Team

Your assessment scores are greatly affected by how well the team members work together, instilling in your students the value of teamwork.


STEM Playground prepares elementary students for team-based STEM competition through activities designed to create excitement about STEM at an early age while assessing and developing the character traits required for effective collaboration.  Through our online virtual STEM tournament, teachers conduct simple, inexpensive science-based activities with their two-student teams, then upload their scores to compare with other teams and classes around the globe.
