Math Grade 8 Term 1
Number Sense and Numeration (Sept. Oct.)
EXPONENTS
- Express repeated multiplication using exponential notation (e.g., 2 x 2 x 2 x 2 = 24 = 24)- Add, Subtract, Multiply and divide exponents
Represent whole numbers in expanded form using powers of ten
- Scientific notation and expanded form
PRIME NUMBERS
- Determine common factors and common multiples using the prime factorization of numbers (e.g., the prime factorization of 12 is 2 x 2 x 3; the prime factorization of 18 is 2 x 3 x 3; the greatest common factor of 12 and 18 is 2 x 3 or 6; the least common multiple of 12 and 18 is 2 x 2 x 3 x 3 or 36)
ORDER OF OPERATIONS
- Solve expressions that involve integers, brackets and exponents using order of operations.
Patterning and Algebra (Oct. November)
- Use algebra in real life situations- Understand the distributive property- Translate word problems into algebraic expressions- Evaluate algebraic expressions with up to three terms (fractions, decimals, integers for variables)
[student is given the terms]- Solve and verify linear equations involving one-variable term and having solutions that are
integers (30x – 5 = 10), by using:a) inspectionb) guess and checkc) a “balance” model
Geometry and Spatial Sense (November)
Angles
- determine the angle relationships for intersecting lines and for parallel lines and transversals and the sum of the angles of a triangle
- Solve angle relationship problems involving triangles, intersecting lines, and parallel lines and transversals

Pythagorean Theorem
- Determine the Pythagorean relationship through investigation- Solve problems involving right triangles using the Pythagorean relationship
Square root
MEASUREMENT (December)

MEASUREMENT (January)
Circles
- Measure the Circumference, radius and diameter of circles using concrete objects (e.g string)- Determine through investigation the relationships for calculating the circumference and the area
of a circle, and generalize to develop the formulas (i.e. circumference of a circle = 3.14 x diameter; area of a circle = 3.14 x (r2)]
- Solve problems involving the estimation and calculation of the circumference and the area of a circle
Cylinders
- Determine through investigation the relationship between the area of the base and height and volume of a cylinder and generalize to develop the formula (Volume = area of base x height)

Graphs
- histogram- bar graph- line graph- stem and leaf- scatter plot- pie chart- Compare graphs (histogram vs. bar graph)

- Collect data by conducting a survey or an experiment – display data in an appropriate graph- Collect data (e.g. Statscan) and display the data in the appropriate charts, tables and graphs - Explain the relationship between a census and a representative sample, sample size and
population- Read, interpret and draw conclusions about data represented in charts, tables and graphs- Identify trends in data- Compare two attributes or characteristics using a scatter plot graph (e.g. gdp per capita and life
expectancy)- Determine the appropriate measure of central tendency (e.g. mean, median or mode) needed to
compare sets of data
Term 2
Number Sense and Numeration (February)
DECIMALS
- Represent, order and compare decimal numbers- Use estimation when solving problems involving decimals- Multiply and divide decimal numbers by various powers of ten- *Change to fractions and percents

RATIOS
- Solve problems involving proportions using a variety of materials (ex. The ratio is 2 to 3 for sand to stone. How much stone is needed if 15 bags of sand are used?)
- Solve problems involving rates (ex. A pack of 24 CDs costs $10.45. A pack of 50 CDs costs $10.45. What is the most economical way to purchase 150 CDs?)
