Explain the difference between finding fractions strips with the same denominator for 1/2+1/3 and 1/2 +1/4
What is : For 1/2+1/4, the 1/4 fraction strips that fit have the same denominator as one of the given denominators. For the 1/2+1/3, the 1/6 fraction strips that fit do no have one of the given denominators.

Lily needs to jog a mile. She first jogs 1/3 and then stops for a break. Next she runs 1/4. How much further does she have left. Use fraction strips to model.
What is 5/12

Nick estimated that 5/8+ 4/7 is about 2. Explain how you know his estimate is not reasonable. What is reasonable?
What is : Both numbers are close to half, so it should be around 1 (A little greater because they are each a little over half)
400
Define: Equivalent Fractions
What is "fractions that name the same amount or part"
400
Define: "Simplest Form"
What is "the form of a fraction in which the numerator and denominator have only 1 as their common factor.

Explain how using fraction strips with like denominators makes it possible to add fractions with unlike denominators. Use 1/2+1/3 to help demonstrate with fraction strips.
What is The fraction strips used to model the addends need to be the same size, so I can combine them and write the sum with one denominator.

Explain how your model for 3/5 - 1/2 is different than your model for 3/5- 3/10. 1. Model with strips 2. Explain
What is Both models use 1/10 strips. The model for -1/2 shows two more 1/10 strips.
500
Explain how you know 4/10+ 2/6 is a little less than 1
What is 4 is close to 5, which is half of ten and 2 is close to 3 which is close to half. Half plus half equals whole, but both numbers are a little short.
