1. What are STEM Bins® Builders Packs?

Designed for ages 5 and up, STEM Bins® Builders Packs include THREE STEM Bins® (stacking cups, snap cubes and star snaps) plus 20 leveled challenge cards per material for a total of 60 building activities!

Challenge cards are double-sided with one-dimensional challenges on one side and more complex, multidimensional challenges on the other side. These options make them easy to differentiate for multiple ages and grade levels!

One of my favorite parts is this GENIUS bin design! The lids for each bin store the cards AND serve as card holders for each challenge!
