A timed sheet on adding 4

Adding 4, from 4 + 0 to 4 + 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 4: all thirteen facts and their answers.

Where adding 4 goes wrong

There are two routes to adding 4 — add 2 twice, or add 5 and take 1 back. The five route is faster but the subtraction step is easy to forget, and then the answer comes out one too big. A whole sheet that is consistently one high is not carelessness, it is that route with its last step missing.

Three that come up

What are the two ways to add 4?
Add 2 twice, or add 5 and take 1 back. The second is faster but has a step to forget.
My child is consistently one too high. Why?
They are adding 5 and skipping the subtraction. The pattern of the error names the strategy.
Is adding 4 related to doubles?
For 4 + 4 yes, and near-doubles like 4 + 5 lean on it directly.
