Carrying, step by step

Carrying (also called regrouping) is the step where a column adds up to ten or more and the extra ten moves to the next column. Sheets set to No carrying keep every column at nine or less, which is the right place to practise lining up digits. With carrying guarantees at least one regroup in every problem.

Once children manage both, leave the option on Some carrying: the mix makes them check each column instead of carrying out of habit.

Which level for which age?

As a rough guide: sums within 10 suit ages 5 to 6, within 20 ages 6 to 7, two-digit column addition ages 7 to 8, and three digits or more from age 8. Every child is different, so the best guide is a sheet they finish with few mistakes in about ten minutes.

Questions from parents and teachers

What is the difference between columns and a row?

In columns the numbers are stacked with ones under ones, the standard written method. In a row the sum is written across, like 34 + 25 = ___, which is better for mental arithmetic.

Why is there an empty square on the left of each column sum?

It leaves room for a carried digit in the answer, for example when 75 + 48 gives a three-digit total. The size of the space never gives the answer away.

Can I make a sheet with no carrying at all?

Yes. Choose No carrying: every column adds up to nine or less on every problem.
