About this math lesson

Counting to 20 is one of the first big milestones in kindergarten math. In this free video, children say each number from 1 to 20 out loud, move their bodies with star jumps and count real objects, which helps them link the number word to the amount.

Key ideas

  • Say the numbers 1 to 20 in order, without skipping
  • Touch or point to one object for each number (one-to-one counting)
  • Notice the teen numbers: 11 to 19 are ten and some more
  • Count backward from 10 for a rocket blast-off

Questions parents and teachers ask

At what age do kids learn to count to 20?

Most children learn to count to 20 between ages 4 and 6. Counting to 20 by rote and counting 20 objects are both kindergarten goals in most US schools.

How can I help my child count past 10?

Point out that the teen numbers are ten and some more, count everyday objects such as steps or snacks, and sing a counting song together a few times a week.
