Look at the domino with the same count on both ends, and the butterfly with matching wings. What do you notice about the two sides?
A double is the same number twice: two matching parts.
Look: two matching rows. What total do they make?
For the last one, say the total before we reveal it.
We build double 2, double 3, double 4 and double 5 together on the ten-frame. Watch the matching rows.
Build a double
In your maths copy, write these two doubles, one under the other:
- 4 + 4 = 8
- 5 + 5 = 10
We check these doubles together on the ten-frame: double 2, double 3, double 4 and double 5. Watch how the matching rows grow.
