Mathematics 8

Unit 1: Number

Big Idea: number represents and describes quantity. Squares, cubes and their roots, percents beyond the usual 0–100 range, proportional reasoning with rates and ratios, and all four operations with fractions.

• Perfect squares and perfect cubes
• Square roots and cube roots

• Percents below 1% and above 100%

• Rates, ratios, proportions, and percent

• Adding, subtracting, multiplying, and dividing fractions

Unit 2: Patterns and Algebra

Big Idea: linear relations can be represented in many connected ways, and generalization often involves representing patterns algebraically and analyzing how change in one quantity affects another. Discrete linear relations, expressions, and two-step equations with integers.

• Linear relations with integers

• Writing and evaluating expressions

• Solving two-step equations with integers

Unit 3: Geometry and Measurement

Big Idea: shape and design can be described, analyzed, and compared. Surface area and volume of prisms and cylinders, the Pythagorean theorem, and constructing and interpreting views and nets of 3D objects.

• Surface area and volume of regular solids

• The Pythagorean theorem

• Building and viewing 3D objects, and their nets

Unit 4: Data and Probability

Big Idea: analyzing data and chance enables us to compare and interpret. Measures of central tendency and theoretical probability with two independent events.

• Central tendency

• Theoretical probability with two independent events

Unit 5: Financial Literacy

Big Idea: financial literacy involves an understanding of the role of money in everyday life. Comparing prices, deals, and value to identify the best buy.

• Best buys
