Operations and Algebraic Thinking
Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each.
Lesson Plans : Worksheets : Activities
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.

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.
Lesson Plans : Worksheets : Activities
Determine the unknown whole number in a multiplication or division equation relating three whole numbers.
Lesson Plans : Worksheets : Activities
Apply properties of operations as strategies to multiply and divide.
Lesson Plans : Worksheets : Activities
Understand division as an unknown-factor problem.
Lesson Plans : Worksheets : Activities
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.

Number and Operations in Base Ten
Use place value understanding to round whole numbers to the nearest 10 or 100.
Lesson Plans : Worksheets : Activities
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.
Lesson Plans : Worksheets : Activities
Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations.

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.
Lesson Plans : Worksheets : Activities
Understand a fraction as a number on the number line; represent fractions on a number line diagram.
Lesson Plans : Worksheets : Activities
Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

Measurement and Data
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, e.g., by representing the problem on a number line diagram.
Lesson Plans : Worksheets : Activities
Measure 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, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.
Lesson Plans : Worksheets : Activities
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.
Lesson Plans : Worksheets : Activities
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.
Lesson Plans : Worksheets : Activities
Recognize area as an attribute of plane figures and understand concepts of area measurement.
Lesson Plans : Worksheets : Activities
Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
Lesson Plans : Worksheets : Activities
Relate area to the operations of multiplication and addition. See related worksheets, workbooks, games, exercises, lesson plans
Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures.
Lesson Plans : Worksheets : Activities
Solve 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.
Lesson Plans : Worksheets : Activities
Geometry
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). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
Lesson Plans : Worksheets : Activities
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.
