## Mathematics

The following are highlights of student learning in Grade 2. They are provided to give teachers and parents a quick overview of the mathematical knowledge and skills that students are expected to acquire in each strand in this grade.

**Number Sense and Numeration:**representing and ordering numbers to 100; representing money amounts to 100¢; decomposing and composing two-digit numbers; investigating fractions of a whole; counting by 1’s, 2’s, 5’s, 10’s, and 25’s; adding and subtracting two-digit numbers in a variety of ways; relating equal-sized groups to multiplication and relating sharing equally to division**Measurement:**measuring length using centimetres and metres; telling time to the nearest quarter-hour; measuring perimeter, area, mass, and capacity using non-standard units; describing and establishing temperature change; choosing personal referents for the centimetre and the metre; comparing the mass and capacity of objects using non-standard units; relating days to weeks and months to years**Geometry and Spatial Sense:**distinguishing between attributes that are geometric properties and attributes that are not geometric properties; classifying two-dimensional shapes by geometric properties (number of sides and vertices); classifying three-dimensional figures by geometric properties (number and shape of faces); locating a line of symmetry; composing and decomposing shapes; describing relative locations and paths of motion**Patterning and Algebra:**identifying and describing repeating patterns and growing and shrinking patterns; developing the concept of equality using the addition and subtraction of numbers to 18 and the equal sign; using the commutative property and the property of zero in addition to facilitate computation

**Data Management and Probability:**organizing objects into categories using two attributes; collecting and organizing categorical and discrete data; reading and displaying data using line plots and simple bar graphs; describing probability, in simple games and experiments, as the likelihood that an event will occur
