# Factors and Multiples

Strand: Number
Outcome: 3

## Curriculum Focus

The changes to the curriculum targeted by this sample include:

• The general outcome focuses on number sense, whereas the previous program of studies specified demonstrating a number sense for decimals and common fractions, exploring integers and showing number sense for whole numbers.
• The specific outcome includes determining multiples and factors of numbers less than 100, identifying prime and composite numbers, and solving problems using multiples and factors. The previous program of studies introduced factors, multiples, primes and composites in Grade 5 and continued to work with them in Grade 6, including common multiples, common factors, least common multiple, greatest common factor and prime factorization using numbers 1 to 100.

Factors and Multiples addresses the following outcomes from the Program of Studies:

Strand: Number
Specific Outcome:

## 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.
