Unit Title: Understanding Division
Time Frame: 20 Days
Grade Level and Subject: Three; Mathematics
Big Ideas/ Enduring Understandings:
How can you use division to find how many in each group or how many equal groups?
Common Core Standards
3.OA.2 Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects
in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56
objects are partitioned in to equal shares of 8 objects each. Froe example, describe a context in which a
number of shares or a number of groups can be expressed as 56 ÷ 8.
3.OA.3 Use multiplication and division within 100 to solve word problems in situations involving equal groups,
arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown
number to represent the problem.
3.OA.5 Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is
known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 ×
5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing
that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive
property.)
3.OA.6 Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number

that makes 32 when multiplied by 8. Multiply and divide within 100.5
3.OA.7 Fluently multiply and divide within 100, using strategies such as the relationship between
multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By
the end of Grade 3, know from memory all products of two one-digit numbers.
