A timed sheet on adding 7

Adding 7, from 7 + 0 to 7 + 12. Every problem on the sheet is drawn from that set and nothing outside it.

Choose 20, 50 or 100 problems and a limit of 1, 2 or 5 minutes, then print the sheet with its answer key on page two, or start the timer and type into the same grid. The problems are drawn again every time the page loads, so a second sheet is not a copy of the first. How the counts and limits work is on its own page, along with what a timed test does and does not measure.

Thirteen rows, with the answers

Adding 7: all thirteen facts and their answers.

Where adding 7 goes wrong

Nearly every cell in the 7s crosses ten, and getting to ten takes 3 — 7 + 5 becomes 7 + 3 + 2. Splitting off a 3 costs an extra beat, so a 7s sheet comes back visibly slower than a 6s sheet from the same child. That slowdown is normal and is not a sign anything has gone wrong.

Three that come up

How do you add 7 to a number quickly?
Take 3 from the other number to make ten, then add what is left. 7 + 6 becomes 10 + 3.
Why is adding 7 slower than adding 5?
The split needs 3, which is less automatic than the 5 a child sees on one hand.
Is a slower time on 7s a problem?
Not by itself. Compare it with the 8s and 9s sheets rather than with the 5s.
