Plus and minus to 20

Twenty-eight mixed problems in two columns. The signs alternate down each column, so every line has to be read before it can be answered.

How to use it

The only sheet here with no picture on it, and that is deliberate: every other sheet gives a child something to count, and at some point the counting has to stop. Mixing the two operations is what makes this practice rather than the same move repeated fourteen times — the sign has to be read on every line, which is exactly what a page of pure addition lets a child skip. Page one never crosses the ten and page two always does, so a child who is not ready for the second page can still finish the first.

Printing notes

  • Print at 100%, not "fit to page" — scaling shrinks the digits and the whole point is that your child writes them at a steady size.
  • Black-and-white and draft mode are fine. Nothing on these sheets depends on colour.
  • Slide a sheet into a punched pocket and a dry-wipe pen turns one page into a hundred goes.
