### Kungfu math p2 slide4 (fraction of a whole)

1. 1. Fractions Fraction of a wholeWhat will we learn today? • Comparing and ordering fractions.
2. 2. Lets do some counting...How many squares are there?
3. 3. But, what if there is only part of asquare?How do we count it?
4. 4. We will use FRACTIONS.Fractions are for counting PART of something.
5. 5. Let’s break the square into parts.There are 4 equal parts in a complete square.
6. 6. How many parts can you see? There is 1 equal part.
7. 7. Here is how we write it.We can write ¼ , which means1 equal parts out of 4 parts.
8. 8. Heres how we write it: ¼We read this like "one fourth."
9. 9. Heres how we write it: ¼The top number is called the numerator We read this like "one fourth."
10. 10. Heres how we write it: ¼The top number is called the numeratorThe top number is called the denominator We read this like "one fourth."
11. 11. Let’s try some more questions.
12. 12. How much is blue?
13. 13. How much is blue?3 pieces are blue out of 4 total pieces.

19. 19. Let’s break it apart. So, ¼ of the square is blue. We read as ‘one fourth’.1 piece are blue out of 4 total pieces.
20. 20. Which of the following figure has agreater fraction? A B
21. 21. Which of the following figure has agreater fraction? A B
22. 22. Which of the following figure has agreater fraction? A B The answer is B. Figure B has 2 yellow parts. Figure A has only 1 yellow part.
23. 23. Peter bought 1 pizza.John ate 1 slice.Mina ate 2 slices.How many slices are there in the pizzaif Peter ate the same number of slicesas John?
24. 24. Peter bought 1 pizza.John ate 1 slice.Mina ate 2 slices.How many slices are there in the pizzaif Peter ate the same number of slicesas John? Peter ate 1 slice of pizza. 1 + 2 + 1 = 4
