Unit 1: Equations and variables

Students learn to evaluate variable expressions by substituting variables with values and applying correct order of operations. They learn to solve equations with one variable and mixed operations.

Unit 2: Geometry

Students learn properties of polygons and classify them as regular, irregular, convex or non-convex polygons. They identify two- and three-dimensional shapes from verbal descriptions, and interpret two-dimensional patterns of three-dimensional objects.

Unit 3: Measurement

Students learn to do calculations with mixed units and apply rounding and approximation to convert between customary and metric units.

Unit 4: Graphs and charts with decimal data

Students learn to organize data with decimal numbers on to various charts. They also learn to read and interpret charts and graphs

Unit 5: Introduction to functions

Students are introduced to the concept of functions. They learn to represent linear functions as tables of input/output values, express functions as equations, and plot functions on a coordinate graph.

Unit 6: Angles and circles.

Students learn about right angles, use of protractor to measure angles, and properties of a circle.

Unit 7: Time

Students learn to convert time among different units of time and represent time as fractions. They understand the concept of time zones and continue to learn to read timetables.

Unit 8: Probability of dependent and independent events

Students learn concepts of dependent and independent events and their probability calculation.

Unit 9: Comparison and ordering


Unit 10: Perimeter and area using units

Students apply unit conversion to calculate perimeter and area.
