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.

Dhoni's Century

One-day match between India and South Africa in Guwahati......., India batting first......

Fill in the blanks:

Dhoni scored 96 +------------- =------------ runs.
How many runs do these players need to complete a century?

	Runs Scored	Runs needed to complete a century
Player 1	93
Player 2	97
Player 3	89
Player 4	99

Numbers are understood not by reciting them in order but by making associations in familiar contexts. Here the idea of a "century" of runs is used. Teachers could add other examples from children's lives to think about 3-digit numbers. Encourage them to speak about large numbers even if they cannot read or write them.

Fill in the blanks:

99-112		195-206
Number(in figures)	Number(in words)	Number(in figures)	Number(in words)
99	Ninety	195	One hundred ninety-five
100	One hundred	196	One hundred ninety-six
101	One Hundred one	197	One hundred ninety-seven
102		198	One hundred ninety-eight
103	One Hundred three		One hundred ninety-nine
104	One Hundred four	200	Two hundred
	One Hundred five	201	Two hundred one
106	One Hundred six
107		203	Two hundred three
	One Hundred eight		Two hundred four
109	One Hundred nine	205	Two hundred five
110	One Hundred ten	206
