Estimation Strategies

Strand: Number
Outcome: 2

Curriculum Focus

This sample targets the following changes in the curriculum:

• The general outcome focuses on number sense; whereas the previous math curriculum specified applying arithmetic operations to whole numbers and decimals, and to illustrate their use in creating and solving problems.
• The specific outcome includes using specific estimation strategies (front-end rounding, compensation and compatible numbers) in problem-solving contexts; whereas the previous math curriculum included estimating, mentally calculating, computing or verifying products (3-digit by 2-digit) and quotients (3-digit divided by 1-digit) of whole numbers.

Estimation Strategies addresses the following outcomes from the Program of Studies:

Strand:	Number
Specific Outcome:	2. Use estimation strategies, including front-end rounding compensation compatible numbers in problem-solving contexts.

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
