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 24hour 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?
