About this worksheet

Each sheet is generated randomly, so you can print a fresh page every day. The link at the bottom of the page reproduces exactly the same sheet if you want to share it with a class.

Each sheet contains 20, 30 or 40 problems (your choice) and is generated at random. Press “New problems” as many times as you like; there is no limit and no account needed.

Worked example

4 + 0 =
  1. Start at the larger number, 4.
  2. Adding 0 changes nothing.
  3. 4 + 0 = 4.

Answer: 4

Teaching tips

  • Use fingers or ten-frames at first, then encourage counting on from the larger number.
  • Time a single sheet once a week rather than every day; progress is more visible.
