What does the Ontario 2020 Mathematics curriculum cover in Grade 3? The 2020 Ontario Mathematics curriculum for Grade 3 covers five strands: Number (place value to 1000, addition and subtraction to 1000, multiplication and division), Algebra (patterns, equations), Data (graphs, collection), Spatial Sense (measurement, geometry), and Financial Literacy (coins, simple budgets). Paperpath worksheets focus primarily on Number and Measurement expectations.
How is Paperpath different from other Ontario Grade 3 worksheet sites? Most free worksheet sites offer generic pages that may not match exactly what your child is learning. Paperpath generates a worksheet matched to your child's grade, province, and current level band — so if your child is working at a support level in multiplication but a stretch level in measurement, each worksheet reflects that. The platform also tracks completions and streaks, so you always know what to do next.
Does Paperpath cover all Ontario Grade 3 math topics? Paperpath currently covers the core Number and Measurement strands for Grade 3 — including place value, addition and subtraction, multiplication, time, and perimeter. Coverage of Data, Algebra, and Financial Literacy strands is being expanded. When you generate a worksheet you can select a specific topic family or let the system choose a balanced mixed-review page.
