[Contributor - Kripa S]
1. Take 2 pens or sticks on one length and 2 more of a different length. Make a rectangle using these 4 sticks. Push two opposite side sticks a little changing its angle from 90 deg. Is it still a rectangle or is it a parallelogram? Push the newly formed shape to the other side to make a different angle. Would it then be called a rectangle? Share your views.
2. Make two teams. One team will draw a quadrilateral on the board, and other team has to identify which one it is. Play this for 5-6 rounds. The team that scores more points wins.
