Use efficient strategies to solve problems
I can use efficient strategies to solve addition and subtraction problems.
Lesson details
Key learning points
- Known facts can be used to help us solve equations and problems efficiently.
- Numbers can be partitioned to bridge ten to help us work efficiently.
- When equations are solved, it is important to choose a strategy that allows you to solve the problem efficiently.
Common misconception
When faced with problems, children may revert to using inefficient counting strategies instead of more efficient calculation strategies.
Record equation required to solve a problem, then explicitly discuss the most efficient strategy to solve it, drawing on prior knowledge and strategies such as use of known facts and the bridge ten strategy.
Keywords
