9.N1 Demonstrate an understanding of powers with integral bases (excluding base 0) and whole number exponents by: representing repeated multiplication using powers; using patterns to show that a power with an exponent of zero is equal to one; and solving problems involving powers.
9.PR3 Model and solve problems using linear equations of the form: ax = b; x/a = b, a ≠ 0; ax + b =c; x/a + b = c, a ≠ 0; ax = b + cx; a(x + b) = c; ax + b = cx + d; a(bx + c) = d(ex + f); and a/x = b, x ≠ 0 where a, b, c, d, e and f are rational numbers.
9.PR7 Model, record and explain the operations of multiplication and division of polynomial expressions (limited to polynomials of degree 1 or 2) by monomials, concretely, pictorially and symbolically.
Use direct and indirect measurement to solve problems
9.SS1 Solve problems and justify the solution strategy using circle properties including: the perpendicular from the centre of a circle to a chord bisects the chord; the measure of the central angle is equal to twice the measure of the inscribed angle subtended by the same arc; the inscribed angles subtended by the same arc are congruent; and a tangent to a circle is perpendicular to the radius at the point of tangency.
9.SP4 Develop and implement a project plan for the collection, display and analysis of data by: formulating a question for investigation; choosing a data collection method that includes social considerations; selecting a population or a sample; collecting the data; displaying the collected data in an appropriate manner; and drawing conclusions to answer the question.
Use experimental or theoretical probabilities to solve problems
9.SP5 Demonstrate an understanding of the role of probability in society.
