Use known addition and subtraction facts within 10 to solve problems
Lesson details
Learning outcome
I can use known addition and subtraction facts within 10 to solve problems.
Key learning points
- Recall addition and subtraction facts within 10 to solve problems.
- Use strategies like near-doubles to solve problems involving numbers within 10
- Use one more, one less or two more, two less to solve problems.
Keywords
Strategy - A plan, a method or a way to solve a problem.
Common misconception
Children may still make errors when selecting the most appropriate strategy to aid their recall e.g. they may see 7 - 2 = and count back in ones rather than seeing that 5 is the odd number before 7
Always talk about the equation to solve, modelling thinking processes e.g. 'I can see... so I know.... The table in the first learning cycle, organising facts by the strategies used to recall them, can be displayed within the learning environment.
Teacher tip
A range of strategies are utilised, but at this point, these can be altered to focus on the individual needs of the children you are working with. The aim is to enable all children to get to the point where they can automatically recall addition and subtraction facts within 10
