**Extended response questions:**  1. How can you tell if two fractions are equivalent? If you multiply or divide one of the numbers eventually they will be the same.

2. When is a fraction in simplest form? When you can't make a fraction any smaller.

3. Why do you need to find a common denominator before adding or subtracting fractions?  if you don't have a denominator it is just the numerators so you can not do the problem. 4. 1/2-->1/4 : 1/4-->1/8 AND 1/3-->1/6 : 1/6-->1/12 Why did you put that answer? What is the relationship between these pairs of fractions? I put this answer because I noticed that you just double the denominator to get the answer.They all double into each other.  5. Crozet Elementary teachers want students to only use #2 pencils or #2 mechanical pencils. To make that happen, the school will now provide all pencils, but we need to figure out what fraction of each kind the school should keep on hand. Several facts are known: 1. Mechanical pencils last twice as long as regular ones. 2. Mechanical pencils may only be used in grades 3, 4, and 5. 3. Mechanical pencils may not be used on bubble tests. 4. There are about the same number of students in grades K-2 as there are in grades 3-5. Using the information provided, what fraction of the total number of pencils should be mechanical pencils? Explain your decision in detail, using the facts. One fourth. half the school uses mechanical pencils because they are the upper grades and They last twice as long as the pencils. The upper graders need to use pencils to fill in bubble sheets because they have more tests.
