Surface Area and Volume

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

Step 2: Determine Evidence of Student Learning

Guiding Questions

  • What evidence will I look for to know that learning has occurred?
  • What should students demonstrate to show their understanding of the mathematical concepts, skills and Big Ideas?

Using Achievement Indicators

As you begin planning lessons and learning activities, keep in mind ongoing ways to monitor and assess student learning. One starting point for this planning is to consider the achievement indicators listed in the Mathematics Kindergarten to Grade 9 Program of Studies with Achievement Indicators. You may also generate your own indicators and use them to guide your observation of the students.

The following indicators may be used to determine whether or not students have met the specific outcome for surface area. Can students:

  • explain, using examples, the relationship between the area of 2-D shapes and the surface area of a given 3-D object?
  • identify all the faces of a given prism, including right rectangular and right triangular prisms?
  • identify all the faces of a given right cylinder?
  • describe and apply strategies for determining the surface area of a given right rectangular or right triangular prism?
  • describe and apply strategies for determining the surface area of a given right cylinder?
  • solve a given problem involving surface area?

The following indicators may be used to determine whether or not students have met the specific outcome for volume. Can students:

  • determine the volume of a given right prism, given the area of the base?
  • generalize and apply a rule for determining the volume of right cylinders?
  • explain the connection between the area of the base of a given right 3-D object and the formula for the volume of that object?
  • demonstrate that the orientation of a given 3-D object does not affect its volume?
  • apply a formula to solve a given problem involving the volume of a right cylinder or a right prism?

Sample behaviours to look for related to these indicators are suggested for some of the activities found in Step 3, Section C, Choosing Learning Activities.
