Grade 3 – Mathematics

Course Overview

The Grade 3 Mathematics course marks an important step in students’ mathematical development as they transition from foundational numeracy toward more strategic problem solving. Building on prior learning, students expand their understanding of number relationships, mathematical operations, and real world applications.

Learners work with larger numbers, explore the four operations, identify patterns, and develop financial literacy through practical scenarios such as shopping, travel, and everyday decision making. Students also strengthen measurement skills and spatial awareness while continuing to build coding knowledge.

As mathematical expectations increase, students are encouraged to explain their thinking, apply logical reasoning, and approach challenges with growing independence.

Important Information

• No prerequisites are required for elementary courses
• Ontario elementary programs do not issue transcript credits

What Students Will Develop

Throughout the course, students deepen mathematical understanding while strengthening analytical and problem solving abilities.

Students will:

• Read, write, compare, and order numbers up to the thousands
• Develop place value understanding across multiple digit numbers
• Solve addition and subtraction problems with increasing accuracy
• Build foundational knowledge of multiplication and division
• Explore equivalent fractions and relationships between wholes and parts
• Identify, extend, and analyze numeric and geometric patterns
• Collect, organize, and interpret data
• Conduct probability experiments and make predictions
• Measure length, perimeter, area, mass, and capacity
• Strengthen spatial reasoning through geometric exploration
• Apply financial literacy skills when working with money
• Expand coding abilities through repeated instructions and loops
• Approach real world problems using flexible strategies

These competencies support mathematical confidence while preparing students for more advanced quantitative reasoning.

Course Structure

Learning is organized into thoughtfully designed units that promote conceptual understanding while maintaining strong engagement.

Counting

Students extend their number sense by reading and writing numbers into the thousands. They explore relationships among ones, tens, hundreds, and thousands while practicing composing, decomposing, comparing, and rounding numbers.

Addition and Subtraction

Learners solve multi digit problems using a variety of tools and strategies. Instruction emphasizes understanding the relationship between operations, using estimation to evaluate solutions, and identifying missing values within equations.

Patterning

Students identify, describe, create, and extend repeating patterns involving numbers and shapes. These experiences support early algebraic thinking and strengthen logical reasoning.

Data

Students sort and categorize information before collecting and displaying data using charts, tables, and graphs. They are introduced to concepts such as mean and mode and use probability experiments to support predictions and interpretation.

Fractions, Multiplication, and Division

Students divide objects into equal parts and investigate equivalent fractions. Instruction focuses on multiplying and dividing numbers from one to ten using manipulatives, patterns, and problem solving strategies grounded in real world contexts.

Shapes

Learners identify and compare polygons, prisms, and pyramids while exploring the properties of two dimensional and three dimensional figures. They examine transformations such as flips, turns, and slides to strengthen spatial reasoning.

Coding

Students expand their computational thinking by designing sequences that include repeated events. They also practice debugging to improve accuracy and logical flow.

Money

Students deepen financial awareness by estimating, counting, and combining coins and bills to represent specific amounts. They apply addition and subtraction when solving authentic financial problems.

Measurement

Learners investigate perimeter, area, mass, capacity, distance, and height using appropriate units. They estimate, compare, and record measurements while selecting tools that best fit each situation.

Social Emotional Learning

Students are encouraged to approach mathematical challenges with persistence and flexibility. By exploring multiple solution pathways, learners recognize that problems can often be solved using different strategies.

Learning Resources

As a fully online course, Grade 3 Mathematics does not rely on a traditional textbook. Students utilize both digital tools and hands on materials to support conceptual understanding.

Recommended resources include:

• A device capable of capturing written work
• Audio recording tools
• Access to a printer
• A binder, folder, or notebook for offline activities
• Household materials that support interactive exploration
• Counters and manipulatives
• A calculator and measurement tools such as rulers or thermometers
• Coins and bills for financial activities
• Basic classroom supplies including paper, scissors, glue, and coloured markers

These materials help students experience mathematics in tangible and meaningful ways.

Teaching and Learning Approach

Our approach blends structured instruction with opportunities for independent problem solving so that students develop both competence and confidence.

Key features of the learning experience include:

• A balance of direct teaching and exploratory learning
• Multi step problem solving experiences
• Technology enriched instruction supported by offline activities
• Real world applications that strengthen relevance
• Guided support from educators and learning coaches

Learning coaches assist students with technical navigation while supporting participation in discussion based activities that reinforce communication skills alongside mathematical understanding.

Preparing Students for Advanced Mathematical Thinking

Grade 3 Mathematics represents a meaningful transition toward deeper quantitative reasoning. As students refine their ability to analyze information, justify solutions, and apply mathematical concepts strategically, they become more independent learners prepared for the expectations of upper elementary education.

At Trinity Ontario Elementary School, mathematics instruction reflects the vision of Trinity Ontario Global Academy by combining academic excellence with the development of confident, capable, and future ready learners.
