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

9
1 whole ½ ½ ¼¼¼ 1/8 ¼ What is 1/2 - 1/8 What is 3/8 - 1/4 What is 2 5/8 - 1 1/2

10
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 2/4 = ½ ½ + ¼ = 3/4 Look Back= neither fraction is greater than 1/2, so the answer should be less than 1.

11
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, ½ = 2/4 2/4 -1/4 = 1/4 = 2 1/4 Look Back= If it were just 5 hrs and 3 hrs, the answer would be 2. So 2 ¼ makes sense.
