Acc6.3 Fractions and Decimals

Lesson 1

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

Lesson 2

  • 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?”.
  • I can explain two ways of interpreting a division expression such as $27 \div 3$.

Lesson 3

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

Lesson 4

  • 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 5

  • 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 6

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

Lesson 7

  • I can describe and apply a rule to divide numbers by any fraction.
  • I can divide a number by a non-unit fraction $\frac ab$ by reasoning with the numerator and denominator, which are whole numbers.

Lesson 8

  • I can solve problems about ratios of fractions and decimals.

Lesson 9

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

Lesson 10

  • I can use division and multiplication to solve problems involving areas of rectangles with fractional side lengths.
  • I can use division and multiplication to solve problems involving areas of triangles with fractional bases and heights.

Lesson 11

  • I can solve volume problems that involve fractions.
  • I know how to find the volume of a rectangular prism even when the edge lengths are not whole numbers.

Lesson 12

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

Lesson 13

  • I can use decimals to make estimates and calculations about money.

Lesson 14

  • I can use diagrams and vertical calculations to represent and reason about addition and subtraction of decimals.
  • I can use place value to explain addition and subtraction of decimals.
  • I know how to solve subtraction problems with decimals that require “unbundling” or “decomposing.”

Lesson 15

  • I can solve problems that involve addition and subtraction of decimals.

Lesson 16

  • I can use area diagrams to represent and reason about multiplication of decimals.
  • I can use place value and fractions to reason about multiplication of decimals.

Lesson 17

  • I can use area diagrams and partial products to represent and find products of decimals.
  • I know how to use a product of whole numbers to find a product of decimals.

Lesson 18

  • I can use long division to find a quotient of two whole numbers when the quotient is a whole number.

Lesson 19

  • I can divide a decimal by a whole number.
  • I can use long division to find the quotient of two whole numbers when the quotient is not a whole number.

Lesson 20

  • I can find the quotient of two decimals.
  • I know how multiplying both the dividend and the divisor by the same factor affects the quotient.

Lesson 21

  • I can use addition, subtraction, multiplication, and division on decimals to solve problems.

Lesson 22

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

Lesson 23

  • I can use the four operations on decimals to find surface areas and reason about real-world problems.
