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.
