Showing 71 - 80 of 155 Standards

Standard Identifier: 3.OA.2

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Represent and solve problems involving multiplication and division.

Standard:
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.

Standard Identifier: 3.OA.3

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Represent and solve problems involving multiplication and division.

Standard:
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.

Footnote:
See Glossary, Table 2.

Standard Identifier: 3.OA.4

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Represent and solve problems involving multiplication and division.

Standard:
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 = ?.

Standard Identifier: 3.OA.5

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Understand properties of multiplication and the relationship between multiplication and division.

Standard:
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.)

Footnote:
Students need not use formal terms for these properties.

Standard Identifier: 3.OA.6

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Understand properties of multiplication and the relationship between multiplication and division.

Standard:
Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8.

Standard Identifier: 3.OA.7

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Multiply and divide within 100.

Standard:
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.

Standard Identifier: 3.OA.8

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Solve problems involving the four operations, and identify and explain patterns in arithmetic.

Standard:
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Footnote:
This standard is limited to problems posed with whole numbers and having whole-number answers; students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations).

Standard Identifier: 3.OA.9

Grade: 3
Domain: Operations and Algebraic Thinking

Standard:
Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.

Standard Identifier: 4.MD.1

Grade: 4
Domain: Measurement and Data

Cluster:
Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.

Standard:
Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), . . .

Standard Identifier: 4.MD.2

Grade: 4
Domain: Measurement and Data

Cluster:
Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.

Standard:
Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.
