Activities to apply knowledge of doubles and doubling
Call out an instruction, for example: Show me double 3. Children hold up 3 fingers on each hand making 6 fingers altogether and say the stem sentence: 3 and 3 is 6. Double 3 is 6. Repeat for different doubles.
Stand facing each other. One of you holds up a number of fingers (1–5) to show the other. Both of you hold up the same number of fingers, like a mirror. Encourage children to say each number and the double they have created.
Spot the double
Call out pairs of numbers, for example: 2 and 3, 5 and 1, 5 and 2, 3 and 3. Children listen and wait to hear a double. When they hear a double, for example: 3 and 3, they jump up and say the stem sentence: Double 3 is 6.
Double ladybirds/ butterflies
Fold an outline of a butterfly or ladybird in half. Paint spots onto one half, fold the paper to find the double.
