Lesson Details
Key learning points
When using column addition, start by adding the numbers with the smallest place value first.
If the sum of the ones or tens digits is ten or greater, regrouping is needed.
Any complete tens are regrouped into the tens column.
Any complete hundreds are regrouped into the hundreds column.
Common misconception
Pupils may make errors with regrouping in the ones and tens, particularly where there is regrouping in both.
Model examples of regrouping with the pupils, including questions where regrouping in the ones causes regrouping in the tens. If necessary, use Base 10 blocks to help with the modelling.
