This course builds on the grade 2 curriculum to further develop students’ understanding of fundamental mathematical concepts by exploring topics related to number sense and numeration, measurement, geometry and spatial sense, patterning and algebra, and data management and probability. Students will work with numbers up to 1000, represent money amounts, continue investigating fractions, and build on addition, subtraction, multiplication, and division skills. Through investigations, students measure distance, perimeter, mass, and capacity using increasing formal units of measurement, identify temperature benchmarks, and develop a further understanding of time. Students begin exploring angles, quadrilaterals, and congruent shapes, continue working with two- and three-dimensional shapes, describe movement, and recognize transformations. Students will continue creating and extending patterns and begin representing geometric patterns in various ways, determine the missing numbers in equations, and investigate the properties of zero and one in multiplication. Students will collect, organize, read, and display data in various types of graphs, establish an understanding of mode, and predict the frequency of an outcome. Throughout the course, students reinforce the mathematical processes of problem-solving, reasoning and proving, reflecting, selecting tools and computational strategies, connecting, representing, and communicating at a developing level. Through investigation of real-life problems, students develop a strong foundation of mathematical knowledge and skills. This course prepares students for grade 4 mathematics. The course relies on the assistance of a learning coach to support young students through the content.Full Grade 3 Mathematics Course Outline

Curriculum Policy Document: The Ontario Curriculum Grades 1-8: Mathematics, 2005 (revised)
Course Developer: Virtual Elementary School
Development Date: 2019
Students learn about representing, comparing, and ordering numbers up to 1000, count by 1s, 2s, 5s, 10s, 25s, and 100s, and count back by 10s, 25s, and 100s. Students will also read and write numbers up to 100, compose, decompose, and round.
In this unit, students add and subtract three-digit numbers mentally using math tools and vertical equations. Students also explore fact families.
Students identify, extend, and create patterns using objects, shapes, and numbers while analysing patterns found on farms.
Students sort, collect, organize, and read data, learn about mode, and explore probability games.
Students investigate fractions, multiplication, and division. Students analyse arrays, equal groups, number lines, and hundreds charts, and solve multiplication and division problems.
In this unit, students describe, compare, sort, and build two-dimensional and three-dimensional shapes, and identify flips, slides, and turns. Students also identify and compare right angles.
Students explore everyday situations related to money to estimate, count, and show money values, and add and subtract money values up to 10 dollars.
Students investigate measurement by examining length, height, and distance, measuring perimeter, area, mass, and capacity, estimating, reading, and recording temperatures, and reading time. Students also solve problems involving time, days, weeks, and years.
The evaluation for this course is based on the student's achievement of curriculum expectations. The final letter grade represents the quality of the student's overall fulfillment of the expectations for the course and reflects the corresponding level of achievement as described in the achievement chart for the discipline. The final grade will be determined based on each of the 8 units (12.5% each) and will reflect the student’s most consistent level of achievement throughout the course, although special consideration will be given to more recent evidence of achievement. There is no final assessment, such as an exam, in this course.
