Welcome to the Pre-Calculus 20 Workshop!

Friday, November 4th, 2011

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

Today’s Plan Teacher Talk Chapter 5: Radical Expressions &

Equations Chapter 6: Rational Expressions &

Equations Chapter 7: Absolute Value & Reciprocal
