Massachusetts Curriculum Frameworks
MA.3.MD. Measurement and Data
3.MD.A. Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
3.MD.A.2. Measure and estimate liquid volumes and masses of objects using standard metric 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 metric units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.
3.MD.B. Represent and interpret data.
3.MD.B.4. Generate measurement data by measuring lengths of objects using rulers marked with halves and fourths of an inch. Record and show the data by making a line plot (dot plot), where the horizontal scale is marked off in appropriate units—whole numbers, halves, or fourths.
