Measurement and Data

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 or hours (e.g., by representing the problem on a number line diagram or clock).3.MD.10Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, exhibiting rectangles with the same perimeter and different areas, exhibiting rectangles with the same area and different perimeters.3.MD.2Estimate and measure liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). (Excludes compound units such as cm^3 and finding the geometric volume of a container.) Add, subtract, multiply, or divide to solve and create 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). (Excludes multiplicative comparison problems [problems involving notions of “times as much.”])3.MD.3Select an appropriate unit of English, metric, or non-standard measurement to estimate the length, time, weight, or temperature (L)3.MD.4Draw 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. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.3.MD.5Measure and record lengths using rulers marked with halves and fourths of an inch. Make a line plot with the data, where the horizontal scale is marked off in appropriate units—whole numbers, halves, or quarters.3.MD.6Explain the classification of data from real-world problems shown in graphical representations. Use the terms minimum and maximum. (L)3.MD.7Recognize area as an attribute of plane figures and understand concepts of area measurement.3.MD.8Measure areas by tiling with unit squares (square centimeters, square meters, square inches, square feet, and improvised units).3.MD.9Relate area to the operations of multiplication and addition.
