Lesson details
Key learning points
- When adding a single digit and a two-digit number, the equation can be solved more efficiently by 'bridging ten.'
- When bridging a multiple of ten, the second addend is partitioned so that it reaches the next multiple of ten.
- Bridging ten is an efficient strategy because number pairs to ten can be used to calculate more easily.
Keywords
Bridge - A mental strategy which uses addition or subtraction to cross a number boundary.
Partition - The act of splitting an object or value down into smaller parts.
Common misconception
Children may partition the second addend in a way that does not allow them to make use of the multiple of ten and use their number bonds to calculate efficiently.
Use ten frames and number lines to support children in finding the multiple of ten and partition the addend in different ways to compare the efficiency of different ways of partitioning.
