Preservation of Equality

Strand: Patterns and Relations (Variables and Equations)
Outcome: 3

Curriculum Focus

This sample targets the following changes in the curriculum:

• The General Outcome is exactly the same as in the previous mathematics curriculum—represent algebraic expression in multiple ways.
• The Specific Outcome focuses on understanding the preservation of equality and solving equations concretely, pictorially and symbolically, whereas the previous mathematics curriculum included solving equations but not specific reference to the preservation of equality.

Preservation of Equality addresses the following outcomes from the Program of Studies:

Strand:	Patterns and Relations (Variables and Equations)
Specific Outcomes:	3. Demonstrate an understanding of preservation of equality by: modelling preservation of equality, concretely, pictorially and symbolically applying preservation of equality to solve equations.

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.

The following steps will help you through the Planning Guide:

• Step 1: Identify Outcomes to Address
• Step 2: Determine Evidence of Student Learning
• Step 3: Plan for Instruction
• Step 4: Assess Student Learning
• Step 5: Follow-up on Assessment
