Grade 1 Mathematics

This course builds on the Kindergarten curriculum to further develop students’ understanding of fundamental mathematical concepts by exploring topics related to number, coding, algebra, data, spatial sense, social emotional learning skills in mathematics, and financial literacy. 

Throughout the course, students will be encouraged to build their social-emotional learning skills by focusing specifically on positive motivation and how to use self-talk strategies to themselves and their peers.

Regarding numbers, students work with numbers up to 50 and learn how to count by various amounts. They learn how we use numbers in everyday life. Students learn basic addition and subtraction strategies. They are also introduced to basic fractions and how to divide shapes into equal parts.

In algebra, students find, continue, and create patterns and show a pattern in different ways. They also begin to work on the idea that in a number sentence, both sides of the equal sign have the same value. Students will begin to write code to order a sequence of steps and to give basic instructions to a computer. They also learn how to find simple errors in code and how to correct them.

In data, students organize data into categories and then display the data to help draw conclusions. They ask and answer questions about data.

In spatial sense, students compare the length, mass, and capacity of different objects and learn how to read a calendar. They also learn how to describe different shapes and figures.

In financial literacy, students learn about Canadian coins and bills and practice comparing their values.

Through investigation of real-life problems, students develop a strong foundation of mathematical knowledge and skills. Students apply mathematical processes and build transferrable critical thinking skills in varied teaching and consolidation activities that appeal to diverse learning styles. Students participate in engaging storylines along with characters who connect their learning to real-world contexts and build confidence by instilling a positive attitude towards mathematics. Various opportunities consolidate students’ learning through technology and offline activities, including tactile manipulatives, to reinforce essential mathematical strategies and tools. The course has a strong focus on reinforcing number sense and numeracy skills. It also provides various activities for practice throughout. This course prepares students for grade 2 mathematics.

Full Grade 1 Mathematics Course Outline

Course Code: MAT1
Curriculum Policy Document: The Ontario Curriculum: Grade 1 Mathematics
Department: Primary
Course Developer: Virtual Elementary School
Development Date: 2020


Students show, compare, order, and read numbers up to 50. Students will estimate amounts up to 50.


Students will count by 1s, 2s, 5s, and 10s to 50. Students will find ordinal numbers, order the months of the year, and read a calendar.


In the patterning unit, students find, describe, and create patterns. Students use shapes, colours, numbers, sounds, and actions to create and analyse patterns around them.

Addition and Substraction

Students develop an understanding of basic addition and subtraction, including utilizing the appropriate symbols. Students learn mental strategies and how to solve word problems.


In this unit students measure attributes of 2D and 3D shapes. They use measure to compare, describe, and order objects.

Shapes, Figures, and Positions

Students sort and build two- and three-dimensional shapes and figures. Students find and describe symmetry in shapes and create symmetrical designs. Students describe locations on maps.

Graphs and Charts

In this unit, students learn about recording, organizing, and reading data in pictographs and concrete graphs. Students also ask and answer questions about graphs.

Composing, Decomposing, and Groups

Students explore composing and decomposing numbers up to 50, and develop a basic understanding of fractions through learning about wholes, halves, and fourths. Students learn how to divide shapes into equal parts.


In the coding unit, students are introduced to coding and learn how to give basic instructions to computers. Students learn how to find and correct mistakes in code.

Likely and Unlikely Events

Students explore probability through examining likely and unlikely events in everyday situations by describing and comparing the likelihood of events.


Students learn about the value of coins and bills. Students count and compare money amounts. Students also solve addition related to money by counting the value of multiple coins.

The Final Grade (Facilitated)

Student evaluation in 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 reflects the student’s most consistent level of achievement across all units in the course, although special consideration is given to more recent evidence of achievement. Students are not required to write a final exam in this course.
