MY ACTIVITY CORNER

What To Do?

To understand the concept of tens and ones

What We Need?

9 rubber bands of two colours each (say red and black), a pencil and a
sheet of paper

How To Do?

• Make groups with 3–5 children in each group.

• Decide which colour rubber bands represent tens and ones

respec vely. Let black rubber bands represent tens and red rubber
bands represent ones.

• Call a group and tell them a number, say 46.

• Using the rubber bands, the Tens Ones

children will represent the given
number in tens and ones. So,

they will have to use 4 black
rubber bands and 6 red rubber
bands to represent 46.

• Ask them the number just before and a er the given number.

• Give marks to each group on the basis of their answers. The group
with the maximum marks will be the winner.
