Comparing number

Hello everyone!
My name is
Allie the Alligator

Before we start, lets learn some
Vocabulary
words

•Compare - to weigh against

is greater than - 6 > 2

is less than - 2 < 6
•is equal to - 2 = 2

Now you know few vocabulary
words in this lesson.
Lets learn
More!

I’m going to help you learn all
about my special symbols.
They look like this!
< >

Take a look at this!
Less than Greater than
< >

The symbols are a bit like my mouth
I am a hungry alligator and I always
want to eat the biggest number.
Smallest number Biggest number
4 < 10

Important note!
Always look at the first set of numbers
from the left side before comparing.

Need some more help?

6 is bigger than 4, so my mouth
wants to eat it!

On your whiteboards can you put my
mouth facing the right direction?
Remember I want to eat the biggest
number!
32 127

32 127
Well done! My mouth is open to eat
127 because it’s bigger than 32.

What about this?
130 99

130 99
Well done! My mouth is open to eat
130 because its bigger than 99.

2 2
Now, What if both numbers are
the same?
I don’t know which
one to eat?

2 = 2
You’re right!
If both numbers
are the same, it
means they are
equal.

Lets try these
examples.
