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.
