How we explain it

Children can open this short lesson before they practice.

  1. Count each thing once. Do not skip any.
  2. To count on, say the next number: 14, then 15.
  3. Counting back goes the other way: 15, 14, 13.

Example: What is 1 more than 14? Count on from 14. The next number is 15. Answer: 15
