Our Mission

STEM Playground is dedicated to fun team-based science technology engineering and math activities that develop character and highlight the value of diversity in teamwork.

How We Align to Standards

STEM Playground designed its STEM activities and supporting curriculum material around you and your students, NOT Common Core standards.  However, we understand the need for those of you in Common Core-participating states to meet English Language Arts and Math standards, even as you teach science.

So STEM Playground asked educational publisher Longbourn Editorial to correlate our current curriculum material to both Common Core and Next Gen Science Standards


How Our Competition Works

STEM Playground’s activities are designed to be completed by teams of two students and will have measurable results which you can compare with other classes globally, nationally, or even within your own community or school.

While you can compare results from just one activity, you can also compete in the cumulative League Challenge by completing all 12 designated League Challenge activities.
