500 pcs BULK STEM KIT for Classrooms

A question we often received years ago was, "How many kits do you need for a Classroom of 30 children". So we decided to create a 500 piece kit that has enough pieces to keep a whole classroom busy building. Team projects are especially fun and it can involve thinking and collaborating at many levels. Build a bridge, a tower or an enormous symmetrical pattern on the gymnasium floor. The pieces are easy to disassemble and will return to the box or a standard 10 gal tub.
