Mixed Numbers and Improper Fractions
SWBAT read and write mixed numbers; rename a mixed number as an improper fraction, and vice versa

Definitions Mixed number Improper fraction
A whole number with a fraction Improper fraction Has a value that is greater than 1. The numerator is greater than the denominator.

Renaming a mixed number as an improper fraction
Multiply the whole number by the denominator Add the product to the numerator Write the sum over the denominator

Examples 7 ½ 8 4/5 5 1/10 22 1/8

To rename an improper fraction as a mixed number
Divide the numerator by the denominator Write the quotient as a whole number Write the remainder over the denominator Reduce it if necessary

Examples 6/5 9/7 11/8 5/3 14/2 48/8

Try These 4 ¼ 2 ½ 2 1/8 12/8 15/9 44/6 17/4 5/2 17/8 1 4/8 = 1 1/2
4 ¼ 17/4 2 ½ 5/2 2 1/8 17/8 12/8 1 4/8 = 1 1/2 15/9 1 6/9 = 1 2/3 44/6 7 2/6 = 7 1/3

SWBAT estimate whether a given fraction is close to 0, ½, or 1
Fraction Sense SWBAT estimate whether a given fraction is close to 0, ½, or 1

Steps Look at the denominator Is the numerator more than half of it?
Is the numerator less than half of it?

Examples 1/8 2/15 6/7 13/15 7/13 8/15

Try These 13/27 17/28 0 or ½ ½ or 1
