Ontario Elementary Grade 3 Mathematics Curriculum
The following are highlights of student learning in Grade 3. 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 1000; representing money amounts to $10; decomposing and composing three-digit numbers; investigating fractions of a set; counting by 1’s, 2’s, 5’s, 10’s, 25’s, and 100’s; adding and subtracting three-digit
numbers in a variety of ways; relating one-digit multiplication, and division by one-digit divisors, to real-life situations
Measurement: measuring distance using kilometres; telling time to the nearest 5 minutes; identifying temperature benchmarks; measuring perimeter using standard units; measuring mass in kilograms and capacity in litres; measuring area using grid paper; comparing the length, mass, and capacity of objects using standard units; relating minutes to hours, hours to days, days to weeks, and weeks to years
Geometry and Spatial Sense: using a reference tool to identify right angles and to compare angles with a right angle; classifying two-dimensional shapes by geometric properties (number of sides and angles); classifying three-dimensional figures by geometric properties (number of faces, edges, and vertices); relating different types of quadrilaterals; naming prisms and pyramids; identifying congruent shapes; describing movement on a grid map; recognizing transformations
Patterning and Algebra: creating and extending growing and shrinking patterns; representing geometric patterns with a number sequence, a number line, and a bar graph; determining the missing numbers in equations involving addition and subtraction of one- and two-digit numbers; investigating the properties of zero and one in multiplication
Data Management and Probability: organizing objects into categories using two or more attributes; collecting and organizing categorical and discrete data; reading and displaying data using vertical and horizontal bar graphs; understanding mode; predicting the frequency of an
outcome; relating fair games to equally likely events
