|3.OA.2… Interpret whole-number quotients of whole |enVisionMath Units: |Pre-test |

|numbers, e.g., interpret 56 ÷ 8 as the number of objects|8-1 Relating Multiplication and Division |Formative assessments: |

|in each share when 56 objects are partitioned equally |8-2 Fact Families with 2, 3, 4, and 5 |Observations, Anecdotal Notes, Exit/Admit Slips, |

|into 8 shares, or as a number of shares when 56 objects |8-3 Fact Families with 6 and 7 |Math Journals, Peer/Self Assessments, Think-Pair-Share, Quizzes |

|are partitioned into equal shares of 8 objects each. For|8-4 Fact Families with 8 and 9 |Post test |

|example, describe a context in which a number of shares |8-5A Making Sense of Multiplication and Division Equations |I Can Statements: |

|or a number of groups can be expressed as 56 ÷ 8. | |θ I can understand division by thinking about how one group can be divided |

|3.OA.3…Use multiplication and division within 100 to | |into smaller groups. 3.OA.2 |

|solve word problems in situations involving equal |θ I can use what I know about multiplication and division to solve word |

|groups, arrays, and measurement quantities, e.g., by |.pdf |problems. 3.OA.3 |

|using drawings and equations with a symbol |θ I can find the answer to a division problem by thinking of the missing |

|3.OA.6… Understand division as an |.pdf |factor in a multiplication problem. (I can figure out 32 ÷ 8 because I know |

|unknown-factor problem. For example, find 32 ÷ 8 by | |that 8 x 4 = 32.) 3.OA.6 |

|finding the number that makes 32 when multiplied by 8. | |θ I can multiply and divide within 100 easily and quickly because I know how |

|3.OA.7… Multiply and divide within 100, using strategies|check My Math for additional resources |multiplication and division are related. 3.OA.7 |

|such as the relationship between multiplication and | | |

|division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ | | |

|5 = 8) or properties of operations. | | |
