ON Grade 1 Math Curriculum
Give your child a strong start in Grade 1 math with lessons and practice that follow exactly what Ontario schools teach, from counting and number sense to patterns and geometry.
About Grade 1 Ontario math
Ontario follows the Ontario Curriculum for mathematics, which organizes learning into strands covering number sense, algebra, data literacy, spatial sense, and financial literacy. In Grade 1, students work on reading and representing whole numbers to 50, adding and subtracting within 20, exploring patterns and equality, sorting data, describing shapes and objects, and comparing lengths, mass, and capacity. StudyPug provides step-by-step lessons and practice problems aligned to every strand so families can support learning at home.
- Strands covered: number sense, algebra, data literacy, spatial sense, and financial literacy
- Step-by-step lessons with worked examples for every Grade 1 topic
- Practice problems and guided exercises matched to Ontario Curriculum expectations
- Aligned to the Ontario Curriculum so every lesson connects directly to what is taught in class

Ontario Grade 1 Math Topics
- Number Sense: Read, represent, compose, decompose, compare, and order whole numbers up to 50; count by 1s, 2s, 5s, and 10s; estimate and verify quantities; explore fair-share and equal-group problems.
- Algebra: Identify and extend patterns; create and translate patterns using movements, shapes, and numbers; recognize variables in symbols; determine equivalent addition and subtraction expressions; identify equivalent relationships among whole numbers up to 50.
- Coding: Solve problems and create computational representations by writing and executing sequential code; read and alter existing code and describe how changes affect outcomes.
- Data Literacy: Sort data by one attribute; collect and record data using tally tables; display data in concrete graphs and pictographs; analyse data and draw conclusions; use terms such as impossible, possible, and certain to describe likelihood.
- Spatial Sense: Sort and construct two-dimensional shapes and three-dimensional objects; describe matching halves; use positional language and follow directions; identify measurable attributes including length, area, mass, capacity, and angle; compare objects by length, area, mass, and capacity.
- Financial Literacy: Identify Canadian coins up to 50 cents and coins and bills up to $50; compare their values.
How StudyPug Helps Ontario Grade 1 Math Students
When your child gets stuck on a Grade 1 concept, StudyPug lets them revisit the lesson at their own pace with clear video lessons and worked examples. You can explore our grade 1 math help to find the exact topic causing difficulty and work through it step by step, or use the grade 1 math practice test to check understanding before a classroom assessment.
Each lesson is broken into small, manageable pieces that match the Ontario Curriculum strands, so children build confidence on one idea before moving to the next. Parents can also follow along to see exactly what their child is learning in class.
