Unit 1 · 3 skills

Measurement

Limits of measuring instruments

The official wording · 3 outcomes
M1
the limitations of measuring instruments, including precision, accuracy, uncertainty
M1
including precision, accuracy, uncertainty, tolerance, and solve problems
M1
the limitations of measuring instruments, including precision, accuracy, uncertainty, tolerance, and solve problems

Key ideas

  1. Precision is how finely an instrument reads; accuracy is how close it is to the true value.

  2. Uncertainty is usually half the smallest division of the instrument.

  3. A precise instrument can still be inaccurate if miscalibrated.

  4. Tolerance is the allowed variation, given as a nominal value plus-or-minus a range.

  5. A part is acceptable if its measurement falls within the tolerance range.

Watch out for

  • Treating precision and accuracy as the same thing.
  • Reporting more digits than the instrument can measure.
  • Accepting a part just outside the tolerance limits.

Unit 2 · 8 skills

Geometry

Triangles, quadrilaterals, and regular polygons

Sine law and cosine law

Transformations of shapes and objects

The official wording · 8 outcomes
G1
Solve problems that involve triangles, quadrilaterals
G1
Solve problems that involve triangles, quadrilaterals, regular polygons
G1
Solve problems that involve triangles, quadrilaterals, regular polygons
G2
Solve problems by using the sine law and cosine law, excluding the ambiguous case
G2
Solve problems by using the sine law and cosine law
G2
Solve problems by using the sine law and cosine law, excluding the ambiguous case
G3
transformations o a 2-D shape or a 3-D object, including translations, rotations, reflections
G3
including translations, rotations, reflections, dilations

Key ideas

  1. A triangle's angles sum to 180°; a quadrilateral's to 360°.

  2. The sine law relates each side to the sine of its opposite angle.

  3. A translation slides; a rotation turns; a reflection flips.

  4. Area formulas differ by shape (triangle, rectangle, trapezoid).

  5. It applies when an angle and its opposite side plus one more part are known.

Watch out for

  • Using 180° for a quadrilateral's angle sum.
  • Pairing a side with a non-opposite angle.
  • Changing the size during a rigid transformation.

Unit 3 · 5 skills

Number

Puzzles and games: logical reasoning

Small-business viability

The official wording · 5 outcomes
N1
Analyze puzzles and games that involve logical reasoning, using problem-solving strategies
N1
puzzles and games that involve logical reasoning, using problem-solving strategies
N2
the viability of small business options by considering expenses, sales, profit or loss
N2
Critique the viability of small business options
N2
Critique the viability of small business options by considering expenses, sales, profit or loss

Key ideas

  1. Logical reasoning rules out impossibilities until the answer remains.

  2. Profit = total sales revenue − total expenses.

  3. Elimination and 'if-then' deductions drive logic puzzles.

  4. Expenses include fixed costs (rent) and variable costs (materials).

  5. A strategy should be tested on cases to confirm it works.

Watch out for

  • Guessing instead of eliminating possibilities logically.
  • Counting only variable costs and ignoring fixed costs.
  • Confusing a lucky solution with a reliable strategy.

Unit 4 · 4 skills

Algebra

Linear relations

The official wording · 4 outcomes
A1
Demonstrate an understanding of linear relations by recognizing patterns and trends, graphing, creating tables of values
A1
linear relations by recognizing patterns and trends, graphing, creating tables of values
A1
creating tables of values, writing equations
A1
writing equations, interpolating and extrapolating, solving problems

Key ideas

  1. A linear relation changes by a constant amount each step.

  2. A table of values lists paired inputs and outputs.

  3. A constant first difference confirms the relation is linear.

  4. Plotting the table's ordered pairs and joining them gives a straight line.

  5. The slope is the constant rate of change; the intercept is the starting value.

Watch out for

  • Calling a relation linear when the differences are not constant.
  • Mixing up the input and output columns.
  • Joining points with a curve instead of a straight line.

Unit 5 · 5 skills

Statistics

Measures of central tendency

Percentiles

The official wording · 5 outcomes
S1
problems that involve measures of central tendency, including mean, median, mode
S1
central tendency, including mean, median, mode, weighted mean, trimmed mean
S1
Solve problems that involve measures of central tendency
S2
Analyze and describe percentiles
S2
Analyze and describe percentiles

Key ideas

  1. The mean is the total divided by the count; the median is the middle value; the mode is the most frequent.

  2. A value's percentile is the percent of data at or below it.

  3. The median resists outliers better than the mean.

  4. The 50th percentile is the median.

  5. The best measure depends on the data's shape.

Watch out for

  • Reporting the mean for strongly skewed data.
  • Reading a percentile as a percent score rather than a rank.
  • Confusing the median position with its value.

Unit 6 · 2 skills

Probability

Interpreting probability

The official wording · 2 outcomes
P1
Analyze and interpret problems that involve probability
P1
Analyze and interpret problems that involve probability

Key ideas

  1. Probability = favourable outcomes divided by total outcomes.

  2. A probability can be written as a fraction, a decimal, a percent, or odds.

  3. Probabilities range from 0 (impossible) to 1 (certain).

  4. A probability describes long-run likelihood, not a guarantee for one trial.

  5. Expected outcomes weigh a value by its probability.

Watch out for

  • Confusing odds with probability.
  • Giving a probability greater than 1.
  • Treating a probability as certainty for a single event.

Unit 7 · 3 skills

Mathematical Research Project

The mathematical research project

The official wording · 3 outcomes
RP1
Research and give a presentation on a historical event or an area of interest that involves mathematics
RP1
Research and give a presentation on a historical event or an area of interest that involves mathematics
RP1
give a presentation on a historical event or an area of interest that involves mathematics

Key ideas

  1. A good research question is focused and genuinely mathematical.

  2. Reliable sources support a strong project.

  3. A plan lists the question, sources, and the mathematics to explore.

  4. Research collects facts and data relevant to the question.

  5. The mathematics of the topic is worked out and checked.

Watch out for

  • Choosing a topic with no real mathematics in it.
  • Starting to research before a focused question is set.
  • Collecting facts without doing any mathematics.
