Trig Ratio Whiteboard Practice

31 May 2015

When I teach trig ratios in geometry, I like to give my students lots of practice in different ways.  I like to get out the individual whiteboards and use this powerpoint for a little quick practice.

The first two slides of the powerpoint give a quick review.  I’ve found that students often have a hard time deciding when to use the inverse function.  I try to remind them at any chance I can.

Then, I give them a quick reminder of the SohCahToa acronym and the trig ratios.

Then, there are some slides with practice problems.  After each practice problem, there is a worked out solution.  It is super handy to have the solutions already typed out.  That way, I can walk around the classroom helping students while everyone else can check their work.

Geometric Transformations Study Guide

22 May 2015

A few times during the school year, I give my students markers and blank paper and walk them through making a study guide for their test.  I’ve written about it before, with my post about a Quadrilaterals Study Guide.

Before my students took their test over geometric transformations, got everything out, but made them make the study guide on their own.  I wasn’t feeling great that day, and didn’t want to go through with what I had planned.  Sometimes, you just have to scrap what you have planned.

I was so impressed with the results!  We had talked quite a bit throughout the year about finding the main ideas in their notes and things like that.  Not only did they do a great job, but they were quiet the whole period and the grades on the test were sky high!  I know that they all did better because they made a study guide on their own.


Here are a few of the study guides that my students made:
