About this worksheet
Twenty-four two-digit problems in columns. Exactly half need regrouping and half do not, shuffled together, so the child has to look at the ones column before deciding what to do.
This is the real test of regrouping. A child who regroups on every problem, or on none, is following a habit rather than reading the numbers. It downloads as a vector PDF, so it prints sharp and light on ink for a class set.
What students will practice
- Add two-digit numbers in columns
- Decide when regrouping is needed
- Check the ones column first
