Unit Overview
In this unit students will:
● Tell and write time to the nearest minute and measure time intervals in minutes.
● Solve elapsed time, including word problems, by using a number line diagram.
● Reason about the units of mass and liquid volume. ○ Understand that larger units can be subdivided into equivalent units (partition).
○ Understand that the same unit can be repeated to determine the measure (iteration).
○ Understand the relationship between the size of a unit and the number of units needed (compensatory principle).
● Graph data that is relevant to their lives. While exploring data concepts, students should Pose a question, Collect data, Analyze data, and Interpret data (PCAI).

Standards
MGSE3.MD.1 Tell and write time to the nearest minute and measure elapsed 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, drawing a pictorial representation on a clock face, etc.
MGSE3.MD.2 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.
MGSE3.MD.3 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. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
MGSE3.MD.4 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.
