Today in Maths, we are recalling number bonds of 20. Here are some activities that you could use at home.
1. Collect 20 items (eg buttons) and use these to find pairs of numbers that make 20. Record the pairs as addition number sentences. Can you record them in a systematic way using a pattern? Highlight the number bonds that you already knew.
2. Using the addition sentences that you have recorded, can you find the subtraction sentences that go with them?
3. Play 'Hit the Button' (link below). Select number bonds of 20 and see how many you can recall in a minute.
4. Try the activities on the worksheet that is attached on this page.
