1. Make multiple chits with different kinds of 2D shapes (circle, square, rectangle, triangle, semicircle). Ask each bench to pick a chit. One student from the bech has to show the 2D shape paper that he will use to make a 3D shape. Second student will draw the equivalent 3D shape as made by the paper, and the other will have to guess the names of the two shapes.
