Lesson details

Key learning points

  1. When the units are the same, you can compare lengths in the same way as we compare 2-digit numbers.
  2. When the units are the same, you can order lengths in the same way as we order 2-digit numbers.
  3. When the units are different and the numbers are the same, you can compare lengths by looking at the unit.

Common misconception

Children may confuse the comparative language of taller, tallest, longer and longest.

Talk about the difference between longest and tallest. Collect examples together and label each object as tallest or longest to support children's understanding.

Keywords

  • Compare - You compare to find out what is the same and what is different. You can compare numbers to find out if one is greater than or less than another.

  • Order - You can order numbers from the smallest to the largest or from the largest to the smallest. The order stays the same when you count.
