UNIT 6 STANDARDS:
Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
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.
Represent and interpret data.
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.
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.
BIG IDEAS
Time…
● The duration of an event is called elapsed time and it can be measured.
Mass and Liquid Volume…
● Mass and liquid volume are important parts of everyday life and can determined a variety of ways.
● Larger units can be subdivided into equivalent units (partition).
● The same unit can be repeated to determine the measure (iteration).
● There is a relationship between the size of a unit and the number of units needed (compensatory principle).
Data and Graphing…
● Charts, tables, line plot graphs, pictographs, Venn diagrams, and bar graphs may be used to display data.
● One way to compare data is through the use of graphs.
● The scale increments used when making a bar graph is determined by the scale intervals being graphed.
ESSENTIAL QUESTIONS
Telling Time…
● What strategies can I use to help me tell and write time to the nearest minute and measure time intervals in minutes?
● How can I use what I know about number lines to help me figure out how much time has passed between two events?
Liquid Volume and Mass…
● What happens when your units of measure change?
● Why is it important to know the mass of an object?
● In what ways can we determine the mass of an object?
● What units are appropriate to measure mass?
● How are units in the same system of measurement related?
● What strategies could you use to figure out the mass of multiple objects?
● What are some ways I can measure the liquid volume?
Graphing and Data…
● · How are tables, bar graphs, and line plot graphs useful ways to display data?
● · How can you use graphs to answer a question?
● · How can surveys be used to collect data?
● · How can surveys be used to gather information?
● · How can graphs be used to display data gathered from a survey?
