Rational Numbers and Square Roots

Strand: Number
Outcomes: 3, 4, 5 and 6

Curriculum Focus

The changes to the curriculum targeted by this sample include:

• The general outcome focus, to develop number sense, has not changed from the previous program of studies.
• The specific outcomes focus is on comparing and ordering rational numbers, operations with rational numbers and order of operations. The focus is also on determining square roots of rational numbers.
• In the previous program of studies, the general outcome focused on the use of a scientific calculator or computer to solve problems involving rational numbers.

Rational Numbers and Square Roots addresses the following outcomes from the Program of Studies:

Strand:

Number

Specific Outcomes:

3. Demonstrate an understanding OF rational numbers by: comparing and ordering rational numbers solving problems that involve arithmetic operations on rational numbers. 4. Explain and apply the order of operations, including exponents, with and without technology. 5. Determine the square root of positive rational numbers that are perfect squares. 6. Determine an approximate square root of positive rational numbers that are non-perfect squares.

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
