Time, Liquid and Mass Measurement and Graphing
Unit description: Students will develop an understanding of how to understand and relate time, liquid, and mass in word problems. Students will also build on their ability to create bar and picture graphs with scales other than one. They will also represent data using line plots.

Essential Outcomes of the Unit
Measurement and Data- Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
- NY-3.MD.1 Tell and write time to the nearest minute and measure time intervals in minutes. Solve one-step word problems involving addition and subtraction of time intervals in minutes.
Measurement and Data- Represent and interpret data.
- NY-3.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 a scaled picture graph or a scaled bar graph.
- NY-3.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.
Other Standards Addressed in the Unit
Measurement and Data- Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
- NY-3.MD.2a Measure and estimate liquid volumes and masses of objects using grams (g), kilograms (kg), and liters (l).
Note: Does not include compound units such as cm3 and finding the geometric volume of a container. - NY-3.MD.2b Add, subtract, multiply, or divide to solve one-step word problems involving masses or liquid volumes that are given in the same units.Note: Does not include multiplicative comparison problems involving notions of “times as much.”
Essential Questions and Big Ideas
How do I solve word problems involving time?
- There are 60 minutes in an hour.
- Number lines can be used to represent time.
How do I solve word problems involving masses and volumes?
- Mass represents how much matter is in an item (similar to weight).
- Volume represents the amount of space a 3-D shape takes up.
How do I represent data using graphs?
- Graphs can model data using scales besides one.
How do I represent data using a line plot?
- Line plots represent numerical data using Xs.
