Comparing Groups of Objects: Less Than.

In this video, we will learn how to compare two groups of up to five objects to see which has less objects. These two jars of candies are equal. Each jar contains the same number of candies. The first jar has three candies, and the second jar has three candies. But if we eat one of the candies from the first jar, the amount of candies in each jar will not be the same anymore. The first jar only has two candies now. This Jar has less candies than the second. The second jar has three candies. It has more candies than the first.

In this video, we’re going to learn different ways to find which group has less. Which jar has less teddy bears? We could use counters to help us compare. Each time we count a teddy bear, we could place a counter. The first jar has one, two, three teddy bears. And the second jar has one, two. Three is more than two, so the first jar has more teddy bears than the second. The second jar has less teddy bears than the first. We can use counters or blocks or other equipment to help us model the numbers in each group. That helps us to compare the groups more easily to see which has more and which has less. Let’s practice comparing groups of objects to find which group has less.

Is the number of apples less than the number of strawberries?

We’re shown a number of apples and a number of strawberries. The question asks us if there are less apples than strawberries. The apples and the strawberries have been matched together using lines. Le-f strawberries. One, two, three, four. There are one, two, three apples. We know there are more strawberries because we can’t match this strawberry to an apple. There aren’t enough apples. Three is less than four. Four is more than three. So the answer to the question, “Is the number of apples less than the number of strawberries?”, is yes because three is less than four.

Which group has fewer birds?

The word fewer is another way to say less. We have to find the group, which has less birds. We could use string and some beads to help us compare the amounts of birds in each group. Each time we count a bird, we could add a bead to the string. Let’s count the birds in the first group. One, two, three, four, five. The first group has five birds. Let’s count the birds in the second group. One, two, three. We’re looking for the group with fewer birds. So we’re looking for the piece of string with the least number of beads. The string with three beads is the shortest. So the group which has fewer birds is the group with three birds. Three is less than five.

Are there fewer dogs than ducks?

To help us answer this question, we need to compare the dogs and the ducks. Let’s make a group of dogs and a group of ducks. There’s one dog, two dogs, three. Now, let’s count the ducks. One, two. The group which has fewest animals is the ducks. Two is less than three. So the answer to the question, “Are there fewer dogs than ducks?”, is no. There are more dogs than ducks. There are fewer ducks than dogs.

In this video, we’ve learned how to compare groups of objects to see which has less.
