Lesson details
Key learning points
- Known strategies can be used to help subtract two 2-digit numbers efficiently.
- It is important to be able to calculate mentally when beginning to subtract two 2-digit numbers.
Keywords
Calculate - To work out an answer, often by adding or subtracting.
Efficiently - Not wasting time or effort. An efficient strategy is one we can carry out easily.
Common misconception
Children do not always make the link to prior learning automatically, so when new numbers are introduced, they can sometimes revert to inefficient strategies.
It is important that the use of efficient strategies that are already known are focused upon when equations with new numbers are introduced so that prior knowledge can be used to support new learning and children can continue to work efficiently.
