Comparing Objects up to 10 Using Symbols.

In this video, we’re going to use these symbols less than, greater than, or equal to to help us compare groups of objects. Here we have two groups of ones bricks. We’re going to compare them. The first thing we need to do is to count how many are in each group. Let’s start by counting this group: one, two, three. Now let’s count the second group. This group has one block. The group with three blocks has the most, and this group has the least number of blocks.

Now we can use one of the symbols less than, greater than, or equal to to compare these two groups of objects. We can think of this symbol like a mouth. It’s open, always hungry, ready to eat the largest amount. This group has the most number of bricks, so the mouth is facing towards the greatest number or the largest number. To read this number sentence, we would say three is greater than one.

Let’s practice with an example question.

Is 10 less than, equal to, or greater than three? Here we have a group of 10 counters and another group with three counters. Which has the most? The group with 10 counters has the most or the greatest number of counters. The open end of the symbol always points towards the greatest number. The number sentence tells us that 10 is greater than three. The correct symbol to use in this sentence is greater than.

Let’s try another example.

This question asks us is 10 less than, equal to, or greater than 10. Here we have two groups, which both have 10 blocks. Both groups have an equal amount. So our sentence reads 10 is equal to 10.

Let’s try one last example.

Is one less than, equal to, or greater than three? In this question, we have to compare one and three. So we have a group with one brick and a group with three bricks. The group with three bricks has the greatest number, and we know that the open end of the symbol always points towards the greatest number. So our number sentence reads one is less than three. The correct symbol in this sentence is less than.

In this video, we’ve learned how to compare groups of objects using the symbols less than, greater than, and equal to.
