# Surface Area and Volume

Strand: Shape and Space (Measurement)
Outcomes: 3, 4

## Curriculum Focus

This sample targets the following changes in the curriculum:

• The general outcome focuses on using direct and indirect measurement to solve problems; whereas the previous mathematics curriculum focused on generalizing patterns and procedures and solving problems involving surface area and volume.
• The specific outcome for surface area focuses on determining the surface area of right rectangular prisms, right triangular prisms and right cylinders to solve problems; whereas the previous mathematics curriculum focused on estimating, measuring and calculating the surface area of any right prism or cylinder and composite 3-D objects.
• The specific outcome for volume focuses on developing and applying formulas for determining the volume of right rectangular prisms, right triangular prisms and right cylinders; whereas the previous mathematics curriculum focused on estimating, measuring and calculating the volume of any right prism or cylinder and composite 3D object.

Surface Area and Volume addresses the following outcomes from the Program of Studies:

Strand: Number
Specific Outcome:
 3 Determine the surface area of: right rectangular prisms right triangular prisms right cylinders to solve problems. 4 Develop and apply formulas for determining the volume of right rectangular prisms, right triangular prisms and right cylinders.

## What is a Planning Guide?

Planning Guides are a tool for teachers to use in designing instruction and assessment that focuses on developing and deepening students' understanding of mathematical concepts. This tool is based on the process outlined in Understanding by Design, by Grant Wiggins and Jay McTighe.
