How we explain it

Children can open this short lesson before they practice.

  1. Compare the tens first. More tens means a bigger number.
  2. If the tens match, compare the ones.
  3. To order numbers, put the smallest first.

Example: Which is bigger: 47 or 53? Tens: 4 tens and 5 tens. 5 tens is more, so 53 is bigger. Answer: 53
