Unit 7 Measurement

Learning Outcomes
At the end of this unit, students should be able to:
• Solve practical problems that involve perimeter, area, and volume in standard units of measure
• Determine the perimeters of polygons
• Estimate and determine the areas of squares, rectangles, and right triangles
• Develop a procedure for determining volume using manipulatives
• Estimate and determine the volume of rectangular prisms
• Describe practical situations where perimeter, area, and volume are appropriate measures to use, and justify orally or in writing
• Identify whether the application of the concept of perimeter, area, or volume is appropriate for a given situation
• Identify equivalent measurement within the metric system for length (millimeters, centimeters, meters, kilometers), mass (grams, kilograms), and liquid volume (milliliters, liters)
• Estimate and measure to solve practical problems that involve metric units of length, mass, and liquid volume
​• Solve practical problems related to elapsed time in hours and minutes within a 24-hour period determining the beginning time, the ending time or the elapsed time

Essential Questions
​• How does what we measure influence how we measure?
 How can you use estimation to support measuring accurately?
• What are the similarities and differences among the measurement attributes (i.e., length, weight, capacity, area, volume, temperature, time)?
• What would influence your decision in choosing a unit of measure?
• In what situations would you need to convert a measurement from one unit to another?
​• How do the known elements change how you model elapsed time?
