# 6.4 Dividing Fractions

### Lesson 1

- When dividing, I know how the size of a divisor affects the quotient.

### Lesson 2

- I can explain how multiplication and division are related.
- I can explain two ways of interpreting a division expression such as $27 \div 3$.
- When given a division equation, I can write a multiplication equation that represents the same situation.

### Lesson 3

- I can create a diagram or write an equation that represents division and multiplication questions.
- I can decide whether a division question is asking “how many groups?” or “how many in each group?”.

### Lesson 4

- I can find how many groups there are when the amount in each group is not a whole number.
- I can use diagrams and multiplication and division equations to represent “how many groups?” questions.

### Lesson 5

- I can find how many groups there are when the number of groups and the amount in each group are not whole numbers.

### Lesson 6

- I can use a tape diagram to represent equal-sized groups and find the number of groups.

### Lesson 7

- I can tell when a question is asking for the number of groups and that number is less than 1.
- I can use diagrams and multiplication and division equations to represent and answer “what fraction of a group?” questions.

### Lesson 8

- I can tell when a question is asking for the amount in one group.
- I can use diagrams and multiplication and division equations to represent and answer “how much in each group?” questions.

### Lesson 9

- I can find the amount in one group in different real-world situations.

### Lesson 10

- I can divide a number by a non-unit fraction $\frac ab$ by reasoning with the numerator and denominator, which are whole numbers.
- I can divide a number by a unit fraction $\frac 1b$ by reasoning with the denominator, which is a whole number.

### Lesson 11

- I can describe and apply a rule to divide numbers by any fraction.

### Lesson 12

- I can use division and multiplication to solve problems involving fractional lengths.

### Lesson 13

- I can use division and multiplication to solve problems involving areas of rectangles with fractional side lengths.

### Lesson 14

- I can explain how to find the volume of a rectangular prism using cubes that have a unit fraction as their edge length.
- I can use division and multiplication to solve problems involving areas of triangles with fractional bases and heights.
- I know how to find the volume of a rectangular prism even when the edge lengths are not whole numbers.

### Lesson 15

- I can solve volume problems that involve fractions.

### Lesson 16

- I can use mathematical expressions to represent and solve word problems that involve fractions.

### Lesson 17

- I can use multiplication and division of fractions to reason about real-world volume problems.
