OctaBlocks$19.95 OctaBlocks are the geometric blocks that really stack up! Six different shapes of prisms - based on two sizes of right triangles, squares (cubes), rectangles, rhombi, and octagons. OctaBlocks are more amenable to construction of true 3-dimensional structures than block sets based on hexagons and equilateral triangles. The edge lengths are 1.6" (4 cm) for the cubes. 34 pieces, with 4 pages of lessons and a plastic storage tub. [ Add to Cart] [ View Cart] |
