3rd Grade Math Common Core Standards

The Common Core State Standards for Grade 3 math can be divided into various domains, each with specific standards and related deliverables. Here’s a table outlining these domains, standards, and deliverables:

Operations and Algebraic ThinkingRepresent and solve problems involving multiplication and division– Interpret products of whole numbers
– Interpret whole-number quotients of whole numbers
– Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities
– Determine 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– Apply properties of operations as strategies to multiply and divide
– Understand division as an unknown-factor problem
Multiply and divide within 100– Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations
Solve problems involving the four operations, and identify and explain patterns in arithmetic– Solve two-step word problems using the four operations.
– Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations.
Number and Operations in Base TenUse place value understanding and properties of operations to perform multi-digit arithmetic– Use place value understanding to round whole numbers to the nearest 10 or 100
– Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
– Multiply one-digit whole numbers by multiples of 10 in the range 10–90
Number and Operations – (Fractions)– Understand 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.
– Understand a fraction as a number on the number line; represent fractions on a number line diagram
– Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
Measurement and DataSolve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects– Tell 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
– Measure and estimate liquid volumes and masses of objects using standard units.
– 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– Draw 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.
– Generate 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– Recognize area as an attribute of plane figures and understand concepts of area measurement
– Measure areas by counting unit squares
– Relate 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– Solve real world and mathematical problems involving perimeters
of polygons
GeometryReason with shapes and their attributes– 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).
– Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole

This table provides an overview of the Common Core framework for Grade 3 math and the expected deliverables for each standard. Note that specific details and additional sub-points may vary depending on the curriculum and resources provided by each state or school district.
