I usually use the last six week of the school year in geometry to teach circles: Arc lengths, chords, secants, tangents, etc. Which I have outlined in the Geometry Planning Guide The following school year students begin Algebra 2 and promptly forget these properties of circles. They also start the new school year frustrated and … Continue reading Going full circle completing the square

For some reason, this school year, I couldn't remember what I'd done in the past and I took this to mean that it wasn't as awesome as it could be. As I … Continue reading Starting Geometry with Definitions

I plan … Continue reading Basic Geometry Constructions 4-tab Foldable

I did this because students sometimes need to be forced to interact with each other and I have a few … Continue reading Day 113: Mean, Median Mode & How to think about data
