Welcome to the Pre-Calculus 20 Workshop! Friday, November 4th, 2011
Jan 02, 2016
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
