Ages: 3+ / Grades: PreK
This series of prisms demonstrates to the child the change in width (breadth), while the length remains constant. Practice with The Brown Stair indirectly prepares the child for concepts in size, sequence, plane geometry, area, and volume. The prisms are crafted in precise progressions from 13/32" x 13/32" x 7-7/8" to 3-15/16" x 3-15/16" x 7-7/8" (1 x 1 x 20 cm to 10 x 10 x 20 cm).

We Know Standards
In the U.S alone, nearly 30% of educational standards are overhauled, revised or edited each year. Tracking these changes demands the full-time expertise and we have the tool to manage those standards, so you can trust us as the leader in standards alignment. Correlations are made for all State, National, and Common Core Standards. In addition, we have Head Start standards for early childhood. And most recently, we’ve added both National STEM Standards and Next Generation Science Standards (NGSS).
