### Do-now: Finding equivalent measurements

As we did in class yesterday, your goal here is to take a measurement in one unit and figure out what it is in another unit be creating another measurement equal in length to the first.

1. 1/4 frips =      gubbles

2. 3/4 gubbles =      frips

3. 1/2 gunfs =      norgs =      boks

### Equivalent Fractions

1. Write each of the fractions or mixed numbers shown below.

2. What does it mean that those fractions are all equivalent?

### Mixed numbers and improper fractions

1. For each of the fraction bars shown below, write the measurement as a mixed number, then change the drawing to turn it into an improper fraction, and write the improper fraction.

2. Below, draw 11/4 gunf, 13/8 norg, and 7/2 bok. Then, next to each, write what it would be as a mixed number.

### Changing the denominator

1. Below, draw fraction bars to show me how to convert: 1 3/4 gunfs into eighths, 2 1/2 norgs into sixths, and 3 3/4 boks into twelfths. You can leave the whole number part undisturbed and convert just the fraction part.

# Equivalent Fractions Homework

1. Write each of the measurements below as a mixed number. Then convert to an improper fraction by first changing the drawing, then writing what it is as a mixed number.

2. Below, draw 13/6 gunf, 15/4 norg, and 7/3 bok. Then, next to each, write what it would be as a mixed number.

3. Convert the fraction parts of each of these measurements into eighths, and write a math sentence showing what the measurement originally was and what you converted it into. (For example, you might write that 4/8 gunf = 2 1/2 gunf)

4. Below, fill in either the numerator or the denominator of each fraction to make all the fractions in each line equivalent.
