Snap, stack and sort! These 100 connecting cubes click together on all sides with a soft, easy snap that little hands can manage. Each cube features 5 geometric shapes (circle, square, triangle, pentagon and hexagon) embossed across 5 of its sides. With 10 different colors, the set works as color sorting toys, shape sorting blocks, counting manipulatives or early math counters. Group by color, link patterns, or organize by both shape and color for more advanced problem solving and reasoning. Use these math blocks at home or in the classroom to teach number sense, patterning, sequencing and early STEAM skills. The included Activity Guide provides ideas for kindergarten, 1st grade and preschool learners at every level. For Ages 3+. || Size: 0.75" sides
