Can you guess
the number of
dots on me ?
And on me?
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.

even if they cannot read or write them.
