1 These numbers are called whole numbers

2 These numbers are called Proper fractions

3 These numbers are called Improper fractions

4 When a number includes both whole numbers and fractions What is it called?

5 It is called a mixed number

6 Here are some mixed numbers

7 How much chocolate?

8 = Whole chocolate bar

9

10

11 If 1 bar contains 4 squares……. = 1 bar of chocolate

13 80 4 = 80 ÷4 = 20

14 Can you do this on your whiteboard? = 1 bar of chocolate 32 6 = ??? Remember: numerator ÷ denominator

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

16 To convert an improper fraction to a mixed number what do you do? If it isnt a whole number then keep the denominator the same. Numerator ÷ Denominator

17 Do some in your book…

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

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

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

21 To convert a mixed number to an improper fraction what do you do? Keep the denominator the same. (Whole number × Denominator) + Numerator
