About

Help Vega the kite-maker sort shape cards by their number of sides, by their side lengths and by their angles, then crack her secret sorting rules. Grade 4 students drag cards into groups, find every shape that fits a rule, and pick the attributes that a set of shapes share. Every direction is narrated, every answer option can be read aloud, and each wrong answer gets a spoken hint. Built for 4.G.A.1 and 4.G.A.2.
