What is on these worksheets?
Each problem gives three numbers, such as 6, 9 and 15. Children complete 6 + 9, 9 + 6, 15 − 6 and 15 − 9. In the triangle style they fill in one missing number instead. In the house style they write all four facts for the numbers in the roof and rooms.
A simple path from easy to harder
- Sums up to 10, complete the triangle. Builds the idea of parts and wholes.
- Sums up to 10, complete each family of facts. Adds the four equations.
- Sums up to 20. Matches the second grade goal of fluency within 20.
- Sums up to 100. For children ready to apply the idea to larger numbers.
Tips
- Link each sheet to a number bond picture or a fact family house.
- Ask children to explain why 9 + 6 and 6 + 9 give the same answer.
- Use the subtraction facts to talk about “what do I add to 6 to make 15?”.
