1. Welcome to the Pre-Calculus 20 Workshop! Friday, November 4th, 2011

2. Today’s Workshop Goals  To become more familiar with the curriculum outcomes and indicators connected to Chapters 5, 6,7  To try some of the “investigate” and “mini- lab” activities that support the curriculum outcomes and inquiry based approach  To network with other teachers in the division that are teaching the course – share ideas, resources, etc

3. Today’s Plan  Teacher Talk  Chapter 5: Radical Expressions & Equations  Chapter 6: Rational Expressions & Equations  Chapter 7: Absolute Value & Reciprocal Functions  Questions  Feedback

4. Pre-Calculus 20 Teacher Talk What is going well? What concerns do you have ? Feedback for publisher/future teachers? What else needs to be addressed during our Interdepartmental meeting time? When should we have our next workshop?
