The start of the second semester has me teaching both Algebra II and Pre-Calculus trigonometry simultaneously. My initial plan is to post material for both classes here. It it becomes confusing or too cumbersome, I’ll split the two classes.

Algebra II

Right Triangle Trigonometry

A foldable on trig concepts seems in order given the amount of material to be reviewed and learned.
