Addition and Subtraction of Positive Fractions and Mixed Numbers

Strand: Number
Outcome: 5

Curriculum Focus

This sample targets the following changes in the curriculum:

• The General Outcome focuses on developing number sense, whereas the previous mathematics curriculum focused on applying arithmetic operations on decimals and integers, and illustrating their use in solving problems.
• The Specific Outcome focuses on understanding adding and subtracting positive fractions and mixed numbers concretely, pictorially and symbolically, whereas the previous mathematics curriculum did not include operations with fractions until Grade 8.

Addition and Subtraction of Positive Fractions and Mixed Numbers addresses the following outcomes from the Program of Studies:

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
