KS1 addition worksheet that helps Year 1 and Year 2 children practise doubling small numbers by writing each sum across a butterfly’s two wings.
Children work through eight printed butterfly sums, doubling each number from 2 to 9 in turn (2 plus 2, 3 plus 3, 4 plus 4, 5 plus 5, 6 plus 6, 7 plus 7, 8 plus 8 and 9 plus 9). Writing the same number on each wing reinforces the link between addition and doubling, while the butterfly format makes the activity feel like a puzzle rather than a drill.
Useful for KS1 mental maths warm-ups, classroom intervention or homework on doubles. Find more addition practice in our addition worksheets for KS1 ages 5 to 7. Printable PDF, A4, downloads instantly after purchase.
