• Comparing and ordering fractions.

2. Let's do some counting...
How many squares are there?

3. But, what if there is only part of a

How do we count it?

4. We will use FRACTIONS.
Fractions are for counting PART of something.

5. Let’s break the square into parts.
There are 4 equal parts in a complete square.

1 equal parts out of 4 parts.

8. Here's how we write it:
¼
We read this like "one fourth."

9. Here's how we write it:
¼
The top number is called
the numerator
We read this like "one fourth."

10. Here's how we write it:
¼
The top number is called
the numerator
The top number is called
the denominator
We read this like "one fourth."

11. Let’s try some more questions.
