About Counting to 20

What this skill is

Counting to 20 expands early counting into the teen decade, requiring children to maintain number sequence beyond ten and represent larger quantities using numerals.

When children learn it

Counting to 20 orally and counting out sets of up to 20 objects is a benchmark kindergarten standard (CCSS K.CC.A.2, K.CC.B.5).

Teaching Tips

  • Count physical steps together while climbing stairs or walking to the car. Pause on 10, have them give a high five, and then count up through 20. Consistent daily counting rhythm builds automatic sequence recall.

Common Mistakes

  • Skipping tricky numbers like 13 or 15 in oral counting recitation.
  • Struggling to count beyond 10 from memory without starting over at 1.
  • Writing teen numbers with reversed digits (such as writing 51 for 15).
