"Learn about 3D shapes (geometric solids) with Choo-Choo train - part 1" is an educational cartoon for preschoolers and children grade 1. In this video Choo-Choo train carries 3d shapes (also called geometric solids) to the same construction site as we've seen in the previous cartoon about 2d shapes. He not only names each shape, but wonderfully explains its properties, and teaches kids how to distinguish it from other solids. Choo-Choo train shows how you can trace 3d shapes in order to see what polygons are in their bases. Children will learn such terms as polygon, base, apex, edges, and will learn about different types of pyramids and prisms (square, pentagonal, hexagonal, and octagonal). This video is also suitable for preschoolers because of the exciting action and cute Choo-Choo train's talking face. Enjoy beautiful 3D animation and nice background music!
