SS Shape and Space

  • SS.1 Use direct and indirect measurement to solve problems.

    • SS.1.1 Solve problems and justify the solution strategy, using the following circle properties:

      • SS.1.1.a the perpendicular from the centre of a circle to a chord bisects the chord.

      • SS.1.1.b the measure of the central angle is equal to twice the measure of the inscribed angle subtended by the same arc.

      • SS.1.1.c the inscribed angles subtended by the same arc are congruent.

      • SS.1.1.d a tangent to a circle is perpendicular to the radius at the point of tangency.

      • SS.1.1.1 Provide an example that illustrates:

        • SS.1.1.1.a the perpendicular from the centre of a circle to a chord bisects the chord.

        • SS.1.1.1.b the measure of the central angle is equal to twice the measure of the inscribed angle subtended by the same arc.

        • SS.1.1.1.c the inscribed angles subtended by the same arc are congruent.

        • SS.1.1.1.d a tangent to a circle is perpendicular to the radius at the point of tangency.

      • SS.1.1.2 Solve a given problem involving application of one or more of the circle properties.

      • SS.1.1.3 Determine the measure of a given angle inscribed in a semicircle, using the circle properties.

      • SS.1.1.4 Explain the relationship among the centre of a circle, a chord and the perpendicular bisector of the chord.

  • SS.2 Describe the characteristics of 3-D objects and 2-D shapes, and analyze the relationships among them.

  • SS.3 Describe and analyze position and motion of objects and shapes.

SP Statistics and Probability

  • SP.1 Collect, display and analyze data to solve problems.

    • SP.1.1 Describe the effect of:

      • SP.1.1.a bias on the collection of data.

      • SP.1.1.b use of language on the collection of data.

      • SP.1.1.c ethics on the collection of data.

      • SP.1.1.d cost on the collection of data.

      • SP.1.1.e time and timing on the collection of data.

      • SP.1.1.f privacy on the collection of data.

      • SP.1.1.g cultural sensitivity on the collection of data.

      • SP.1.1.1 Analyze a given case study of data collection; and identify potential problems related to bias, use of language, ethics, cost, time and timing, privacy or cultural sensitivity.

      • SP.1.1.2 Provide examples to illustrate how bias, use of language, ethics, cost, time and timing, privacy or cultural sensitivity may influence data.

    • SP.1.2 Select and defend the choice of using either a population or a sample of a population to answer a question.

      • SP.1.2.1 Identify whether a given situation represents the use of a sample or a population.

      • SP.1.2.2 Provide an example of a situation in which a population may be used to answer a question, and justify the choice.

      • SP.1.2.3 Provide an example of a question where a limitation precludes the use of a population; and describe the limitation, e.g., too costly, not enough time, limited resources.

      • SP.1.2.4 Identify and critique a given example in which a generalization from a sample of a population may or may not be valid for the population.

      • SP.1.2.5 Provide an example to demonstrate the significance of sample size in interpreting data.

    • SP.1.3 Develop and implement a project plan for the collection, display and analysis of data by:

  • SP.2 Use experimental or theoretical probabilities to represent and solve problems involving uncertainty.

    • SP.2.4 Demonstrate an understanding of the role of probability in society.

      • SP.2.4.1 Provide an example from print and electronic media, e.g., newspapers, the Internet, where probability is used.

      • SP.2.4.2 Identify the assumptions associated with a given probability, and explain the limitations of each assumption.

      • SP.2.4.a Explain how a single probability can be used to support opposing positions.

      • SP.2.4.3 Explain, using examples, how decisions may be based on a combination of theoretical probability, experimental probability and subjective judgement.
