About this worksheet

Twenty vertical problems, four to a row, with a rounded box under each one for the sum. The mix runs from easy starters like 4 + 2 and 6 + 0 up to 9 + 8 and 10 + 10, with a few doubles scattered through. A pencil and an eraser cheer from the corners, and there is a star to color at the bottom once the page is done.

It works well as a five-minute warm-up at the start of a math lesson, or as morning work. The page is black and white line art, so it is light on ink when you need a stack of them.

What students will practice

  • Add within 20
  • Practice doubles like 7 + 7 and 8 + 8
  • Add 0 and add to 10
