Measurement and Data

3.MD.1Tell and write time to the nearest minute and measure time intervals in minutes. Solve elapsed time word problems on the hour and the half hour, using a variety of strategies.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.3.MD.3Draw scaled picture graphs and scaled bar graphs to represent data sets 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 in appropriate units—whole numbers, halves, or quarters.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.3.MD.8Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths. Find an unknown side length. Exhibit rectangles with the same perimeter and different area or with the same area and different perimeters.
