Exponents

Strand: Number
Outcomes: 1 and 2

Curriculum Focus

The changes to the curriculum targeted by this sample include:

• There is a change from integral exponents in the previous program of studies to whole number exponents in the revised program of studies, so students are no longer working with negative exponents in Grade 9.
• This outcome has an increased focus on connections, communication and technology.

Exponents addresses the following outcomes from the Program of Studies:

Strand:

Number

Specific Outcomes:

1. Demonstrate an understanding of powers with integral bases (excluding base 0) and whole number exponents by: representing repeated multiplication, using powers using patterns to show that a power with an exponent of zero is equal to one solving problems involving powers. 2. Demonstrate an understanding of operations on powers with integral bases (excluding base 0) and whole number exponents: (am)(an)=am+n am ÷ an = am – n, m > n (am)n = amn (ab)m = ambm;

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
