She has dots on her body.
Have you ever noticed the number of dots?

Let us Play
The child with more number of coloured boxes will win.
D. Play with your friend. Roll the dice and colour a box with the same number of dots as on the dice. Take turns with your friend and roll again.
Choose the colour and fill it in the below boxes.
My colour 
Friend’s colour
Use the dot and colour flash cards to help children gain instant recognition of numbers without counting. This is called subitization. Make more cards with dot patterns of numbers 1 to 9 in different designs and sizes as required.
Vanishing Buttons
Gola monkey wears his favourite shirt with four buttons. He went to the garden and ate too many bananas as he was fond of them. What do you think happened then?
One of the buttons popped out and rolled away. But he cannot dream of giving up bananas and he keeps on losing all the buttons one by o

Discuss the number of buttons left on the shirt at the end. Ask children to name objects, things around them whose number is zero. Let children understand that zero is also a number like one, two and other numbers. Discuss with children about the benefits of balanced diet and ill-effects of overeating.
Write ‘0’
Think and Tell
A. How many suns do you see in the night?
B. How many moons do you see at noon?
Use concrete objects to demonstrate the idea of zero by reducing one object each time. Discuss the situations where something is absent and its number is called as ‘zero’ like there are 0 buses in the classroom. Also encourage children to count backwards from 5 to 0 initially and later from 9 to 0.

Have a discussion to help children to understand and remember the number partitions of 5 and 10. For example, if the teacher says 2, the child should respond 3, when doing partitions of 5. Similarly, if the teacher says 4, the child should respond 6, when doing partitions of 10. This is the time when children start counting beyond 10. Draw attention towards the fact that there is always a number one more than the previous number.

Help the children to count concrete objects up to 20 using groups of ten and units. Give them a handful of seeds or buttons not more than 20. Ask them to guess the number first, then group and count. How close was the guess? Let children reason out the basis for their guesses.

E. A group of friends while playing built some towers.
i. Tick 
the tallest tower.
ii. Which tower used the most number of blocks? Write the number of blocks used in it.
iii. Which tower used the least number of blocks? Write the number of blocks used in it.
Let us Do
i. 8, 12, 6
ii. 14, 11, 19
B. Circle the biggest number.i. 16, 19, 11
ii. 11, 17, 9
C. Find the numbers hidden under the paw.
D. Write the numbers from the biggest to the smallest.
11, 3, 16, 20, 13, 9
Let children find out their ways to decide which number is bigger. Ask them why have they decided so. The children must understand that 15 is bigger than 11 because it is 4 more than 11 and similarly for other numbers up to 20.
i. Number of blocks
ii. Number of white dots
F. Join the numbers from 1 to 20.
Project WorkA. Find out the things from your surroundings that are in the group of 10. For example, bindi cards having bindis in the groups of 10.
B. Ask children to make their own number cards 10 to 20. They can use old cardboards, waste materials, etc.
Encourage children to recognise the group of 10, while counting the objects beyond 10.
