Teaching Subtraction with Regrouping
What it is
Eight subtraction problems within 20, some needing a borrow, each checked by adding back, and a story problem.
When a child is ready
Ready once subtraction within 10 is quick and the child knows a ten is ten ones.
If they struggle
Use the page's own words: if the top number is too small, borrow from your neighbor. The check sum shows at once whether the borrow was done right.
