Unit 5 Area and Geometric Measurement: Volume Grade 5 Math 

Unit Length and Description:
10 days
Students’ prior work with the area model prepares students for work with area and volume in Unit 5. Students will recognize volume as an attribute to solid figures as they learn that a 1 unit by 1 unit by 1 unit cube (a cubic unit) is the standard unit for measuring volume. Students will find the volume of a rectangular prism by counting unit cubes. Students will practice measuring volume using cubic centimeters, cubic inches, cubic feet, and improvised units. Work will also involve applying the formulas V = l x w x h and V = b x h. In Unit 5, students will select appropriate units, strategies, and tools for solving real word problems involving estimating and measuring volume. This work will include situations where students find the volume of figures composed of two right rectangular prisms. Work with area and volume also reinforces recently learned fraction concepts and scaling. Questions about how the area changes when a rectangle is scaled by a whole or fractional scale factor may be asked and missing fractional sides may be found.


Standards:


Enduring Understandings:
· Volume is represented in cubic units. · Volume can be expressed in both customary and metric units. · A square unit could have fractional lengths. As long as the lengths of a square unit are the same, it is still considered a square unit.

Essential Questions:
· How do I use the language of math to make sense of/solve a problem? · How can the volume of cubes and rectangular prisms be found? · What is the relationship among the volumes of geometric solids? · Why is volume represented with cubic units and area represented with square units? · How do you find volume using fractional lengths?
