**What are odd numbers?**

Odd numbers are whole numbers that cannot be divided exactly into pairs.

Odd numbers, when divided by 2, leave a remainder of 1.

1, 3, 5, 7, 9, 11, 13, 15 … are sequential odd numbers.

Odd numbers have the digits 1, 3, 5, 7 or 9 in their ones place.

*One, three, five, seven and nine,*

*All standing in a straight line.*

*Divide them into equal teams,*

*One is left, and alone it seems!*

## Let's do it!

Put an odd number of beads in a box. Ask your child to count and determine if the total number of beads is even or odd. Next, give your child two empty boxes. Instruct him/her to divide the beads into the two boxes such that each of them have equal number of beads. Ask how many are left.

Further, ask your child to pick out an even number of beads and then, an odd number of beads. Show that the sum or difference of an even and odd number is odd.
