Number Sense and Numeration | Numération et sens du nombre

Number sense refers to a general understanding of numbers and operations. Numbers are used in describing quantities, in counting, and in carrying out numerical operations such as addition, subtraction, multiplication, and division. Understanding numbers and how they relate to each other, and knowing how to combine them to solve problems, help students develop understanding in all areas of mathematics.

Highlights of student learning across grades 1-8 include:

  • decomposing, composing, representing and ordering numbers;

  • representing money amounts;

  • developing the concept of place value;

  • investigating, representing, comparing and ordering fractions;

  • using exponential notation;

  • adding, subtracting, multiplying and dividing (numbers, decimals, fractions and integers);

  • applying order of operations (BEDMAS:B-brackets, E-exponents [powers, roots], DM- divide or multiply [left to right], AS-add or subtract [left to right]) ;

  • relating numbers, fractions, decimals, and percents;

  • representing proportional relationships (fractions, decimals, percents, unit rates and ratios).
