Welcome to Grade 8 Math. Grade 8 Mathematics An Overview of the Year Term 1: Begin September with: 1. Number Sense (5 weeks) □ Rounding □ Place value □ Expanded form using powers of ten □ Multiplying and Dividing by base tens □ Scientific notation □ Metric conversions □ Prime and composite numbers □ Prime factor ladders – looking for the prime factors of whole numbers □ Square roots □ Imperfect squares □ Perfect squares □ Squares □ Integers □ Adding integers (concrete and numerical models) □ Subtracting integers (concrete and numerical models) □ Multiplying integers (concrete and numerical models) □ Dividing integers (concrete and numerical models) □ Order of operations with integers □ Solving problems with integers 2. Measurement - Circles (3 weeks) □ Radius of a circle formula (r = d/2) □ Diameter of a circle formula (d=2r or d=C/π) □ Circumference of a circle formula (C=πd or C=2πr) □ Area of a circle formula (A = πr²) □ Value of π (pi) □ sentences (“little ones”) for all questions. If asked a question, full sentence in words is required. □ Round to the nearest tenth □ Solving circle problems 3. Geometry - Angle Relationships (3 weeks) □ Complementary angles □ Supplementary angles □ Opposite angles □ Transversals □ Co-interior angles □ Alternate angles □ Corresponding angles □ Show all work when calculating an unknown angle measure. 4. Probability (2 weeks) □ tree diagrams (titles underlined and there must be an outcomes column) □ P(event) = fraction = decimal = percent □ Odds in favour of an event (favourable : unfavourable) □ Odds against an event (unfavourable : favourable) 5. Data Management (2 weeks) □ Spend a lesson on reviewing graphs (circle, bar, line, pictograph) □ Relate census and sample □Measures of central tendency □ Inferring and Evaluating data □ Scatter plots □ Shape of Data □ Stem and Leaf Charts / Frequency Tables / Histograms Term 2: Begin in January with: 6. Patterning (2 weeks) □ Four models – concrete, graphical, numerical, and pattern rule □ Term & Value t-charts □ Iterative rule □ Explicit rule □ Linear vs Non-linear graphs 7. Algebra (3 weeks) □ Solving equations with multiple steps concretely (with the step-by-step process in both words and algebra tiles) – a check must be present □ Solving equations with multiple steps numerically – a check must be present □ Balance problems (showing all your work) □ Solving word problems in Algebra (Need a “Let” statement(s), your equation, a check, and a therefore sentence) 8. Number Sense – Fractions (5 weeks) □ Adding fractions □ Subtracting fractions □ Multiplying fractions (concrete and numerical models) □ Dividing fractions (concrete and numerical models) □ Order of operations with fractions □ Solving fraction problems Number Sense – Proportional Reasoning □ Ratios □ Rates □ Proportions □ Word problems with proportional reasoning 9. Geometry - Pythagorean Theorem (2-3 weeks) □ Labeling a right angle triangle first with a (leg), b (leg), c (hypotenuse). □ Using the formula a² + b² = c² (and being able to isolate legs if necessary) for both length and area. □ Using units of measurement □ Rounding to the nearest hundredth □ Using therefore sentences at all times. □ Solving Pythagorean problems 10. Measurement – Cylinders (2-3 weeks) □ Surface area of cylinders □ Volume of cylinders □ Problems that include the SA and V of cylinders Here is the link to the Grade 8 Math website! :) |
