Bigger or Smaller

Compare and order numbers

What your child practices

Comparing and ordering numbers, using <, > and =, and noticing numbers close to 50.

Minnesota K-12 Academic Standards benchmark: 2.3.6.1 · comparing two- and three-digit numbers using hundreds, tens and ones

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
