Let's do some counting...How many squares are there?
![Page 3: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/3.jpg)
But, what if there is only part of a square? How do we count it?
![Page 4: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/4.jpg)
We will use FRACTIONS.
Fractions are for counting PART of something.

Let’s break the square into parts.
There are 4 equal parts in a complete square.
![Page 6: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/6.jpg)
How many parts can you see?
There is 1 equal part.

Here is how we write it.
We can write ¼, which means
1 equal parts out of 4 parts.

Here's how we write it:
¼We read this like "one fourth."
![Page 9: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/9.jpg)
Here's how we write it:
¼We read this like "one fourth."
The top number is called the numerator

How much is blue?
![Page 13: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/13.jpg)
How much is blue?
3 pieces are blue out of 4 total pieces.
![Page 14: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/14.jpg)
How much is blue?
3 pieces are blue out of 4 total pieces.
So, ¾ of the square is blue.

Let’s break it apart.
1 piece are blue out of 4 total pieces.
![Page 19: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/19.jpg)
Let’s break it apart.
1 piece are blue out of 4 total pieces.
So, ¼ of the square is blue.
We read as ‘one fourth’.

Peter bought 1 pizza.John ate 1 slice.Mina ate 2 slices.How many slices are there in the pizza if Peter ate the same number of slices as John?
![Page 24: Kungfu math p2 slide4 (fraction of a whole)](https://reader034.vdocuments.us/reader034/viewer/2022042715/559c26021a28ab482c8b45e4/html5/thumbnails/24.jpg)
Peter bought 1 pizza.John ate 1 slice.Mina ate 2 slices.How many slices are there in the pizza if Peter ate the same number of slices as John?
1 + 2 + 1 = 4
Peter ate 1 slice of pizza.
