Beginning geometry students get a hands-on introduction to solid forms with this tub of 3D plastic shapes. The 80 pieces include 8 each of 10 different geometric shapes from cones, spheres and cylinders to cubes, pyramids and more. The set is perfectly sized for desktop use. Geometric shapes set are a great tool to identify the different attributes of each shape, because students can see the shapes from each angle. Students can compare the shapes in the set with every day objects or find the number of faces and edges each shape has, to find out what makes each shape unique. The shapes can even be used for physics classes, to identify the shapes that easily roll, slide or can be stacked. By tracing the outline of the shapes, student can compare 2D and 3D shapes. The cylinder is 2.5cm tall. Ages 7+ years.
