### 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.

- 5 1/4 frips =
__ __ gubbles

- 4 3/4 gubbles =
__ __ frips

- 1 1/2 gunfs =
__ __ norgs = __ __ boks

### Equivalent Fractions

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

- What does it mean that those fractions are all
**equivalent**?

### Mixed numbers and improper fractions

- 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.

- 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

- 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

- 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.

- 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.

- 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
*2 4/8 gunf = 2 1/2 gunf*)

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