3.M.3.NF Number and Operations-Fractions

3.M.3.MD Measurement and Data

  • 3 Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.

    • 3.M.3.MD.1 tell and write time to the nearest minute, measure time intervals in minutes and solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

    • 3.M.3.MD.2 measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg) and liters (l) and 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.

  • 3 Represent and interpret data.

    • 3.M.3.MD.3 draw a scaled picture graph and a scaled bar graph to represent a data set with several categories and solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs.

    • 3.M.3.MD.4 generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch and show the data by making a line plot, where the horizontal scale is marked off in appropriate units—whole numbers, halves or quarters.

  • 3 Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

    • 3.M.3.MD.5 Recognize area as an attribute of plane figures and understand concepts of area measurement.

    • 3.M.3.MD.6 Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).

    • 3.M.3.MD.7 Relate area to the operations of multiplication and addition.

      • 3.M.3.MD.7.a Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.

      • 3.M.3.MD.7.b Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

      • 3.M.3.MD.7.c use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c and use area models to represent the distributive property in mathematical reasoning,

      • 3.M.3.MD.7.d recognize area as additive and find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.

  • 3 Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures.

3.M.3.G Geometry

  • 3 Reason with shapes and their attributes.

    • 3.M.3.G.1 understand that shapes in different categories (e.g., rhombuses, rectangles and others) may share attributes (e.g., having four sides), 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.

    • 3.M.3.G.2 partition shapes into parts with equal areas and express the area of each part as a unit fraction of the whole.
