Class Notes

The McGraw-Hill Ryerson PreCalculus 12 Text is used as the Main Resource.

Assignments in the Powerpoint Lesson Plans refer to pages and questions in the PreCalculus 12 text.

Pedagogical Shifts: TRANSFORM, Moving from Traditional to Student-centered

Shifting from content based to competencies based

Shifting from Student as Knowledge Recipient to Student as Inquirer and Creator

Shifting from Memorization to Higher-level Thinking

Shifting from One-size-fits-all to Personalized, Differentiated

Building and Solving Equations Activity Template

I used, this template as an introduction to Solving Exponential Equations. Students had to build exponential equations starting from x = #. For example, x = 3, In the next step, multiple by 2 to get 2x = 6. Add 3 to both sides, 2x+3 = 9. Finally raise each side of the equation to a base: 5^(2x+3) = 5^9.  I had students switch papers and them solve the equation by undoing the steps in the reverse order. I liked how students were able to justify the strategy of equating the exponents when the bases are the same.
