1. Essential Questions for the Fraction Unit Part II:1. How do I recognize what strategy to use for a specific problem?2. How are fractions used and applied in the larger world?3. Why study fractions?4. What do good problem solvers do?

2. Learning Target:Students will learn how to compute the actual sums and differences of fractions with common denominators.

3. What do the parts of a fraction tell us?Denominator –Numerator –

4. How do we read/count fractions?http://wme.lzu.edu.cn/kimpton/img/fractions1.gif

5. Why did we find it necessary to find a common denominator when comparing fractions?

6. When we have common denominators it makes adding and subtracting of fractions very easy to do.You just add or subtract the numerators and leave the denominator the same sense all the pieces are cut into the same size.

10. How do you simplify a fraction?

11. Find the difference. Simplify if possible.8/9 – 2/9

12. Find the difference. Simplify if possible.8/9 – 2/9 = 6/9 = 2/3

13. Find the sum or difference. Simplify if possible.9/10 + 3/105/8 + 1/85/7 + 6/75/6 – 1/68/9 – 2/97/12 – 5/12

14. Find the sum or difference. Simplify if possible.9/10 + 3/10 = 12/10 = 1 2/10 = 1 1/55/8 + 1/8 = 6/8 = 3/45/7 + 6/7 = 11/7 = 1 4/75/6 – 1/6 = 4/6 = 2/38/9 – 2/9 = 6/9 = 2/37/12 – 5/12 = 2/12 = 1/6

15. A costume pattern uses ¾ yard of velvet ribbon. You have only ¼ yard of ribbon. How many yards of ribbon do you need?

16. A costume pattern uses ¾ yard of velvet ribbon. You have only ¼ yard of ribbon. How many yards of ribbon do you need?¾ - ¼ = 2/4 = ½½ yd

17. Can you compute the actual sums and differences of fractions with common denominators?
