Grade 3 Math

Below is a simplified list of the Math curricular units and core competencies for Grade 3. 


The Alberta curriculum is complex and lengthy and in order to present a coherent and understandable document, I have omitted many of the non-content specific skills and attitudes discussed in the original curricular documents.

Specific Outcome 9

Demonstrate an understanding of addition and subtraction of numbers with answers to 1000 (limited to 1-, 2- and 3-digit numerals), concretely, pictorially and symbolically, by:

• using personal strategies for adding and subtracting with and without the support of manipulatives
• creating and solving problems in context that involve addition and subtraction of numbers.

Note: Students investigate a variety of strategies, including standard/traditional algorithms, to become proficient in at least one appropriate and efficient strategy that they understand.

Specific Outcome 10

Specific Outcome 11

Demonstrate an understanding of multiplication to 5 x 5 by:

• representing and explaining multiplication using equal grouping and arrays
• creating and solving problems in context that involve multiplication
• modelling multiplication using concrete and visual representations, and recording the process symbolically
• relating multiplication to repeated addition
• relating multiplication to division.

Understand and recall multiplication facts to 5 x 5.

Specific Outcome 12

Demonstrate an understanding of division (limited to division related to multiplication facts up to 5 x 5) by:

• representing and explaining division using equal sharing and equal grouping
• creating and solving problems in context that involve equal sharing and equal grouping
• modelling equal sharing and equal grouping using concrete and visual representations, and recording the process symbolically
• relating division to repeated subtraction
• relating division to multiplication.

Understand and recall division facts related to multiplication facts to 5 x 5.

Specific Outcome 13

Demonstrate an understanding of fractions by:

• explaining that a fraction represents a part of a whole
• describing situations in which fractions are used
• comparing fractions of the same whole that have like denominators.

Patterns & Relations - Patterns (Gr. 3)

General Outcome: Use patterns to describe the world and to solve problems.

Specific Outcome 1

Demonstrate an understanding of increasing patterns by: Describing, Extending, Comparing, Creating numerical (numbers to 1000) and non-numerical patterns using manipulatives, diagrams, sounds and actions.

Specific Outcome 2

Demonstrate an understanding of decreasing patterns by: Describing, Extending, Comparing, creating numerical (numbers to 1000) and non-numerical patterns using manipulatives, diagrams, sounds and actions.

Specific Outcome 3

Sort objects or numbers, using one or more than one attribute.

Patterns & Relations - Variables & Equations (Gr. 3)

General Outcome: Represent algebraic expressions in multiple ways.

Specific Outcome 4

Solve one-step addition and subtraction equations involving a symbol to represent an unknown number.

Shape & Space - Measurement (Gr. 3)

General Outcome: Use direct and indirect measurement to solve problems.

Specific Outcome 1

Relate the passage of time to common activities, using nonstandard and standard units (minutes, hours, days, weeks, months, years).

Specific Outcome 2

Relate the number of seconds to a minute, the number of minutes to an hour and the number of days to a month in a problem-solving context.

Specific Outcome 3

Demonstrate an understanding of measuring length (cm, m) by:

• selecting and justifying referents for the units cm and m
• modelling and describing the relationship between the units cm and m

Demonstrate an understanding of measuring mass (g, kg) by:

• selecting and justifying referents for the units g and kg
• modelling and describing the relationship between the units g and kg
• estimating mass, using referents
• measuring and recording mass.

Specific Outcome 5

Demonstrate an understanding of perimeter of regular and irregular shapes by:

• estimating perimeter, using referents for cm or m
• measuring and recording perimeter (cm, m)
• constructing different shapes for a given perimeter (cm, m) to demonstrate that many shapes are possible for a perimeter.

Shape & Space - 3-D Objects & 2-D Shapes (Gr. 3)

General Outcome: Describe the characteristics of 3-D objects and 2-D shapes, and analyze the relationships among them.

Specific Outcome 6
