Game 1
Let us clap

(iii) When the teacher stops clapping, all the students should stand on any one of the shapes, as they like.
(iv) Now the teacher can show any one of the shape cards. Then the students who are standing on the particular shape will clap and say the name of it loudly (Eg: If the teacher shows the 'square' card, the students standing on the 'square' shape will clap and say the name 'square' loudly).
(v) Teacher can continue the game till the students get familiarized with all the shapes.
Game 2

Procedure:
(i) Divide the students into two or three groups according to the strength of the class.

(iii) Teacher can appreciate the group which forms the said shape correctly and quickly.
