2. These numbers are called Proper fractions1 2 3 15 12 22 2 3 5 6 4 7

3. These numbers are called Improper fractions4 2 25 15 30 22 9 3 7 6 10 7

4. When a number includes both whole numbers and fractions1 1 2
What is it called?

5. It is called a mixed number1 1 2

6. Here are some mixed numbers5 4 9 2 1 3 3 2 5 2 1 4 1 6 8

= ??? 6

15. Can you do this on your whiteboard? 32 6
= 1 bar of chocolate 32
32 ÷ 6 = 5r2 = 5 2 = 6 6
Remember: The denominator stays the same

16. If it isn’t a whole number then keep the denominator the same.
To convert an improper fraction to a mixed number what do you do?

18. But, how do you convert a mixed number to an improper fraction?2
= ? 1 2

19. 2 groups of 2 with 1 remaining.5
(2 x 2)+1 = 5 = 2

20. 5
= ? 3 4 23
(5 x 4)+3 = 23 = 4 23 = 3
23 ÷ 4 = 5r3 = 5 4 4
