Grade 8 Mathematics

This course enables students to deepen their understanding of mathematical concepts related to Number Sense and Numeration, Measurement, Geometry and Spatial Sense, Patterning and Algebra, and Data Management and Probability. Students will gain a thorough understanding of the different representation of numbers and use this understanding to extend their knowledge into sequences and solving algebraic expressions. Students will also focus on geometric properties of circles and polygons through investigation and applications. Through practical examples, students will analyze different sets of data and make conclusions based on the results. Throughout this course students will reason mathematically and communicate their thinking as they solve multi-step problems.

Number Sense and Numeration

Representing and ordering rational numbers; representing numbers using exponential notation; solving multi-step problems involving whole numbers and decimals; multiplying and dividing fractions and integers; multiplying and dividing decimals by powers of ten; applying order of operations in expressions with brackets and exponents; solving problems involving percents to one decimal place and percents greater than 100; solving problems involving rates and proportions.

Measurement

Converting between cubic centimetres and cubic metres and between millilitres and cubic centimetres; developing circumference and area relationships for a circle; developing and applying the formula for the volume of a cylinder; determining and applying surface-area relationships for cylinders.

Geometry and Spatial Sense

Sorting quadrilaterals by geometric properties involving diagonals; constructing circles; investigating relationships among similar shapes; determining and applying angle relationships for parallel and intersecting lines; relating the numbers of faces, edges, and vertices of a polyhedron; determining and applying the Pythagorean relationship geometrically; plotting the image of a point on the coordinate plane after applying a transformation.

Patterning and Algebra

Representing the general term in a linear sequence, using one or more algebraic expressions; translating statements, using algebraic equations; finding the term number in a pattern algebraically when given any term; solving linear equations involving onevariable terms with integer solutions using a “balance” model.

Data Management and Probability

Collecting categorical, discrete, and continuous data; organizing data into intervals; displaying data using histograms and scatter plots; using measures of central tendency to compare sets of data; comparing two attributes using data management tools; comparing experimental and theoretical probabilities; calculating the probability of complementary events.

The Final Grade

The evaluation of the student’s achievement in this course is based on the student’s achievement of the curriculum expectations. The percentage grade represents the student’s overall achievement and reflects the corresponding level of achievement as described in the Achievement chart for this discipline. The final grade for this course is calculated based on each of the five units (20% each) which are broken down as such: Knowledge & Understanding Set 10%; Mid-Unit Test 30%; Thinking & Communication Set 10%; Application Assignment 10%; Final Unit Test 40%
