# Multiplication and Division Part B

Strand: Number
Outcomes: 6, 7

## Curriculum Focus

This sample targets the following changes in the curriculum:

• The General Outcome focuses on number sense, whereas the previous mathematics curriculum specified applying arithmetic operations on whole numbers and illustrating their use in creating and solving problems.
• The Specific Outcome for multiplication focuses on using personal strategies, arrays, estimating, connecting concrete and symbolic representations, and the distributive property, whereas the previous mathematics curriculum was limited to connecting manipulatives, diagrams and symbols.
• The Specific Outcome for division includes using personal strategies with and without concrete materials, estimating, and relating division to multiplication, whereas the previous mathematics curriculum focused on connecting manipulatives, diagrams and symbols as well as the connections between multiplication and division.

Multiplication and Division Part B addresses the following outcomes from the Program of Studies:

Strand: Number
Specific Outcomes:
 6 Demonstrate an understanding of multiplication (2- or 3‑digit by 1-digit) to solve problems by: using personal strategies for multiplication with and without concrete materials using arrays to represent multiplication connecting concrete representations to symbolic representations estimating products applying the distributive property 7 Demonstrate an understanding of division (1-digit divisor and up to 2-digit dividend) to solve problems by: using personal strategies for dividing with and without concrete materials estimating quotients relating division to multiplication.

## 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.
