Comparing objects to 100

Home learning focus

In this lesson you will learn to compare different numbers of objects to 100 using the less than (<) and more than (>) signs.

This lesson includes:

  • two videos
  • two activities

Learn

In this lesson we will compare different numbers using counting. You will use a number line to help your thinking.

A number that comes first on the number line is smaller than the numbers that come after.

Think about ways to compare groups of objects while watching the first video.

You could guess which group is larger, but it is more accurate to count how many objects are in each group and compare the numbers on a number line.

In the next video you will compare two more groups of objects using a number line.

Also think about how you could use partitioning to compare the numbers by making each number from base 10 equipment.
