Ontario math curriculum for grade 1
Grade One – Overall Expectations for Math Skills

Below is a quick checklist for parents to use as a reference for the Ontario Curriculum math starting from grade one.

There are different learning strands for the Ontario math curriculum, which means your child might excel in some rather than others, and that is absolutely expected! Not all students excel in all learning strands at once. However, over the years, they do strengthen it with practice.

Here we go:


By the end of Grade 1, students will:

• Read, represent, compare, and order whole numbers to 50, and use concrete materials to investigate fractions and money amounts;

• Demonstrate an understanding of magnitude by counting forward to 100 and backward from 20

• Solve problems involving the addition and subtraction of single-digit whole numbers, using a variety of strategies.


  • Estimate, measure, and describe length, area, mass, capacity, time, and temperature, using non-standard units of the same size
  • Compare, describe, and order objects, using attributes measured in non-standard units.


  • Identify common two-dimensional shapes and three-dimensional figures and sort and classify them by their attributes;*
  • Compose and decompose common two-dimensional shapes and three-dimensional figures;
  • Describe the relative locations of objects using positional language.


  • Identify, describe, extend, and create repeating patterns;
  • Demonstrate an understanding of the concept of equality, using concrete materials and addition and subtraction to 10.

Data Management

  • Collect and organize categorical primary data and display the data using concrete graphs and pictographs, without regard to the order of labels on the horizontal axis;
  • Read and describe primary data presented in concrete graphs and pictographs;
  • Describe the likelihood that everyday events will happen.

Math and Language are by far the most concerning subjects for parents which is why I’ve put this post together for your own reference.
