Lesson details
Key learning points
- Number facts to 10 can be applied to multiples of 10
- Using pairs to 10 and pairs to 100 we can find pairs to 100
- If we have a pair to 10 then the tens have to total 90 for the whole to be 100
- A number line can represent the complements to 100
Keywords
Complement to 100 - Pairs of numbers which total 100
Total - The result of adding.
Common misconception
Pupils may be less efficient if they are not fluent with bonds within 10 e.g. 3 + 6 = 9
Provide additional scaffolding as appropriate including examples of pairs that total 9 and 10
