Common Core Standards

OA — Operations & Algebraic Thinking

Represent and solve problems involving multiplication and division.
  • 3.OA.1Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each.
  • 3.OA.2Interpret 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.
  • 3.OA.3Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities.
  • 3.OA.4Determine the unknown whole number in a multiplication or division equation relating three whole numbers.
Understand properties of multiplication and the relationship between multiplication and division.
  • 3.OA.5Apply properties of operations as strategies to multiply and divide. Examples: Commutative property, Associative property, Distributive property.
  • 3.OA.6Understand 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.
  • 3.OA.7Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
Solve problems involving the four operations, and identify and explain patterns in arithmetic.
  • 3.OA.8Solve 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.
  • 3.OA.9Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations.

NBT — Number & Operations in Base Ten

Use place value understanding and properties of operations to perform multi-digit arithmetic.
  • 3.NBT.1Use place value understanding to round whole numbers to the nearest 10 or 100.
  • 3.NBT.2Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
  • 3.NBT.3Multiply one-digit whole numbers by multiples of 10 in the range 10–90 using strategies based on place value and properties of operations.

NF — Number & Operations—Fractions

Develop understanding of fractions as numbers.
  • 3.NF.1Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
  • 3.NF.2Understand a fraction as a number on the number line; represent fractions on a number line diagram.
  • 3.NF.3Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

MD — Measurement & Data

Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
  • 3.MD.1Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes.
  • 3.MD.2Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units.
Represent and interpret data.
  • 3.MD.3Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs.
  • 3.MD.4Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units—whole numbers, halves, or quarters.
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
  • 3.MD.5Recognize area as an attribute of plane figures and understand concepts of area measurement.
  • 3.MD.6Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
  • 3.MD.7Relate area to the operations of multiplication and addition.
Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures.
  • 3.MD.8Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

G — Geometry

Reason with shapes and their attributes.
  • 3.G.1Understand 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). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals.
  • 3.G.2Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.
