Grade 2 is where mathematical thinking starts to deepen in ways that matter for the long term. Numbers stretch past 100 for the first time. Addition and subtraction become more flexible and strategic. Patterns evolve from simple repetition into rules and predictions. For parents trying to understand what their child is working on \u2014 or where they might need extra support \u2014 this guide covers every strand of the Ontario Grade 2 math curriculum clearly and in full.<\/p>\n\n\n\n

Ontario Grade 2 math curriculum: the six strands<\/h2>\n\n\n
\n
\"Grade<\/figure>\n<\/div>\n\n\n

The Ontario 2020 math curriculum organises learning into six strands from Grade 1 through Grade 8. In Grade 2, all six are active throughout the year.<\/p>\n\n\n\n

Strand B: Number<\/h2>\n\n\n
\n
\"Number<\/figure>\n<\/div>\n\n\n

Number is the largest and most foundational strand in Grade 2. It covers number sense (B1) and operations (B2).<\/p>\n\n\n\n

B1: Number sense<\/h3>\n\n\n\n

Whole numbers to 200<\/strong><\/p>\n\n\n\n

In Grade 2, students read, represent, compose, and decompose whole numbers up to and including 200. They use place value to understand two- and three-digit numbers \u2014 recognising that 143 means 1 hundred, 4 tens, and 3 ones \u2014 and they compare and order numbers on number lines and in different contexts.<\/p>\n\n\n\n

This is a major step up from Grade 1, where the ceiling was typically numbers to 50. Students who are not confident with place value at three digits will find addition and subtraction of larger numbers significantly harder.<\/p>\n\n\n\n

Even and odd numbers<\/strong><\/p>\n\n\n\n

Students identify and describe even and odd numbers, and explore patterns in sequences of even and odd numbers. This connects directly to early multiplication concepts \u2014 even numbers can always be split into pairs.<\/p>\n\n\n\n

Fractions<\/strong><\/p>\n\n\n\n

Grade 2 introduces fractions as equal parts of a whole. Students learn to recognise and name halves, thirds, and fourths (quarters) in shapes and sets of objects. The emphasis is on understanding that fractions represent fair sharing \u2014 that each part must be equal.<\/p>\n\n\n\n

Skip counting<\/strong><\/p>\n\n\n\n

Students skip count by 2s, 5s, 10s, and 25s, both forward and backward. Skip counting by 2s and 5s builds fluency with multiplication concepts; skip counting by 25s connects directly to money (quarters). See skip counting worksheets here<\/a>.<\/p>\n\n\n\n

B2: Operations<\/h3>\n\n\n\n

Addition and subtraction to 100 and beyond<\/strong><\/p>\n\n\n\n

Grade 2 students add and subtract two-digit numbers with and without regrouping, and extend this to three-digit numbers in contexts where regrouping is not required. The curriculum emphasises a range of strategies \u2014 not just one prescribed algorithm \u2014 including:<\/p>\n\n\n\n
