Operations and Algebraic Thinking | 3.OA |
Represent and solve problems involving multiplication and division. | |
1. Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7. | |
CCCs linked to 3.OA.A.1 | 3.NO.2d1 Find the total number of objects when given the number of identical groups and the number of objects in each group, neither number larger than 5. |
3.NO.2d2 Find the total number inside an array with neither number in the columns or rows larger than 5. | |
3.NO.2d3 Solve multiplication problems with neither number greater than 5. | |
3.PRF.1d1 Use objects to model multiplication and division situations involving up to 5 groups with up to 5 objects in each group and interpret the results. | |
4.NO.2d6 Find total number inside an array with neither number in the columns or rows larger than 10. | |
4.NO.2d8 Match an accurate addition and multiplication equation to a representation. | |
4.PRF.1d2 Use objects to model multiplication and division situations involving up to 10 groups with up to 5 objects in each group and interpret the results. | |
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 into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8. | |
CCCs linked to 3.OA.A.2 | 3.NO.2d4 Determine how many objects go into each group when given the total number of objects and the number of groups where the number in each group or number of groups is not greater than 5. |
3.NO.2d5 Determine the number of groups given the total number of objects and the number of objects in each group where the number in each group and the number of groups is not greater than 5. | |
3.PRF.1d1 Use objects to model multiplication and division situations involving up to 5 groups with up to 5 objects in each group and interpret the results. | |
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. | |
CCCs linked to 3.0A.A.3 | 3.NO.2e1 Solve or solve and check one- or two-step word problems requiring addition, subtraction or multiplication with answers up to 100. |
4. Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = _ ÷ 3, 6 × 6 = ?. | |
CCCs linked to 3.0A.A.4 | 4.NO.2d7 Determine how many objects go into each group when given the total number of objects and the number of groups where the number in each group or number of groups is not greater than 10. |
Understand properties of multiplication and the relationship between multiplication and division. | |
5. Apply properties of operations as strategies to multiply and divide. 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). | |
CCCs linked to 3.OA.B.5 | 3.PRF.2d2 Apply properties of operations as strategies to multiply and divide. |
6. Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8. | |
CCCs linked to 3.OA.B.6 | 3.NO.2d4 Determine how many objects go into each group when given the total number of objects and the number of groups where the number in each group or number of groups is not greater than 5. |
3.NO.2d5 Determine the number of groups given the total number of objects and the number of objects in each group where the number in each group and the number of groups is not greater than 5. | |
Multiply and divide within 100. | |
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. | |
CCCs linked to 3.OA.C.7 | None |
Solve problems involving the four operations, and identify and explain problems in arithmetic. | |

9. Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that four times a number is always even, and explain why four times a number can be decomposed into two equal addends. | |
CCCs linked to 3.OA.D.9 | 3.PRF.1e1 Describe the rule for a numerical pattern (e.g., increase by 2, 5 or 10). |

Geometry | 3.G |
Reason with shapes and their attributes. | |
1. Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals).
