Doubles addition colour by code — butterfly

The six doubles from 3+3 to 8+8 map to six answers and six colours exactly as on the rocket sheet, so a parent can alternate the two across a week and get real spaced repetition on the same six facts rather than a single one-off practice.

Because the picture only resolves once enough correct answers are coloured in, a child who is guessing produces a visibly unfinished or wrong-looking butterfly well before the last cell — which is what makes this a genuine check rather than a coincidental colouring page.
