Odd or Even?
What your child learns
Deciding whether a group of up to 20 objects is odd or even by pairing them up or counting by 2s, and writing an even number as the sum of two equal addends.
Try it at home
Pair up socks or shoes: if one is left without a partner, the number is odd. Then write it down, like 12 = 6 + 6.
