KS1 addition worksheet that uses a hundred square to help Year 1 and Year 2 children add 10 to any number with confidence.
Children use the hundred square at the top of the page to answer fifteen add 10 sums, including 5 plus 10, 9 plus 10, 12 plus 10, 20 plus 10, 17 plus 10, 25 plus 10, 28 plus 10, 39 plus 10, 60 plus 10, 74 plus 10, 85 plus 10, 33 plus 10, 59 plus 10, 14 plus 10 and 31 plus 10. Two follow-up questions ask children what they notice about the answers and whether they can spot a quick way of adding 10 without using the square, which moves the lesson on from picture support to mental method.
Useful for homework after a place-value lesson, parent-led practice at home or small group intervention. More addition work sits in the addition worksheets for KS1 ages 5 to 7. Printable PDF, A4, downloads instantly after purchase.
