Focus classroom attention on prisms with this set of 16 blue bases and 34 yellow faces. During the physical construction of the prisms students can develop their mathematical vocabulary by communicating what pieces they need. Students will also learn why the shape is defined as a prism and explore surface area, volume and more. Set contains 2 each of small equilateral triangles, large equilateral triangles, right angle triangles, pentagons and hexagons with 4 isosceles triangles, 15 squares and 21 rectangles, allowing eight different prisms to be consructed. Combine the blue bases to create many other prisms. Includes 12-page teacher's guide.
