Less, greater in ten groups

Teaching Transcript

🎙️

Let's compare these two ten groups and see whether the first group is less than, greater than, or equal to the second group

For comparing two numbers, we start with the largest place value, in this case the tens. We have 2 tens on each side, so the tens are equal. We can move to the next place value, the ones.

In the first group, we have 5, and in the second group we have 6, so the first group is less than the second

We can think of the less than and greater than signs as being like alligators. They eat the larger amount, so the less than sign opens its alligator mouth towards the second group

This math skill teaches how to compare two numbers by examining them place value by place value, starting with the highest (tens). If tens are equal, the ones place is then compared. The "<" symbol is metaphorically described as an alligator that "eats" the larger number.
