Closer to 0Closer to ½Closer to 1 1 whole 3/6 is = to ½. 1/5 is 1 part away from zero 9/10 is 1 part away from zero 5/10 is one half. 5/9 would be a little more than 1/2 4 6 1 5 5 9 4 6 0 1212 1 1 5 9 10 9 5 9

Understand: order children from least to greatest Plan: Compare each fraction to the 0, ½ and 1 Solve: 0-----------------------------------------------------1. 1/4 Tim 7/12 Karen 2/3 Randy 5/6 Devon Look Back= double check it is least to greatest, match fractions to names

10
1 whole ½ ½ ¼¼¼ 1/8 ¼ What is 1/8 + 1/4? What is 3/8 + 1/2? 1/8 ¼ ½ + ¼ + ½

11
Ex: Adding w/in Fraction Families Understand: How much in all- add the fractions Plan: What do I know about 4ths and 8ths? Solve: 2/8 = ¼ 1/4 + 2/4 = 3/4 1/8 ¼ ¼¼¼¼¼¼ Look Back= neither fraction is greater than 1/2, so the answer should be less than 1.

12
1/3 1 whole 1/3 1/6 1/12 What is 2/3 - 1/6 ? What is 2/3 - 2/12 ? 1/6 1/3 1/6 1/12 1/3 1/12

13
Understand: How much more? Subtract the fractions Plan: What do I know about 3rds and 6ths? Solve: Look Back= 5/6 is almost 1 whole. Taking away 1/3 would leave about ½, so 3/6 makes sense. Susan spent 1/3 hour researching a social studies project on Monday and 5/6 hour on Tuesday. How much more time did she spend working on her project on Tuesday than Monday? 1/3 1/6 1/3 1/6 1/3 1/6

14
Ex: Subtracting w/in Fraction Families Understand: How much more? Subtract the mixed numbers Plan: subtract the whole numbers, then the fractions Solve: 5-3 = 2, Look Back= If it were just 5 hrs and 3 hrs, the answer would be 2. So 2 ¼ makes sense. ½ ¼¼ = 2 ¼
