About this worksheet

Start with "Numbers up to 5" for the first weeks, then 10. For children who count on their fingers, 12 problems is a full session; the 20-problem version is for the end of the year or first grade review. Press New version for a fresh sheet with the same settings — the facts are reshuffled so every fact within the limit comes up before any repeats.

The columns layout ("5 over 3 with a line") is also available for schools that introduce it early.

Standards

  • Common Core K.OA.A.2 — solve addition problems within 10
  • Common Core K.OA.A.5 — fluently add within 5

Questions

How many problems should a kindergartener do?

Ten to twelve in one sitting, untimed. Fluency within 5 is the kindergarten goal; sums to 10 are practised but not expected to be automatic until grade 1.

Do the problems include zero?

Yes, a few: "4 + 0" and "0 + 4" appear, as the standard asks, but never "0 + 0".
