Dot Game
Guess the number of dots in the circle. Now count and check your guess. Play this game with your friends by making circles.
See who can guess best.
Children need interesting exercises to help them with visual estimation of numbers of things arranged randomly and in symmetrical groups. Teachers could use other instances, such as bundles of leaves sold in the market, the school assembly, designs on mats, etc. to make them guess and estimate different numbers. In this book an ant has been used to show the child that a guess or estimate has to be made.
