Addition fact · ten plus

7 + 10 = 17

Seven plus ten equals seventeen. One number is 10, so there's nothing to work out: 17 simply means 1 ten and 7 ones.

See 7 + 10

7 red and 10 yellow. The first frame fills up at 10, and 7 more sit in the next one.

Ten and some more

  1. One ten-frame is full: that's the 10.
  2. 7 more counters sit in the next frame.
  3. Read it as a place-value name: ten and seven is seventeen, written 17.
Another way

The 1 in 17 is the ten and the 7 is the ones. Writing it the other way round is a common slip with teen numbers.
