After determining how to write the equations of circles through the Shell Center activity: Equations of Circles 1, my students needed to practice using equations of circles. I decided to find my high school on Google Maps and make a screenshot. I then imported the screenshot into Desmos and adjusted the size of the image … Continue reading Sprinkler System Design

# Day 155 & 156: The Triplets of Cellville

I chose this Mathalicious lesson because we have not used circles enough in my geometry classes. We stared the school year with constructions, but haven't used them much this semester and I wanted them to recall and extend prior learning. I also wanted students to gain more experience modeling real world scenario's with mathematics & … Continue reading Day 155 & 156: The Triplets of Cellville

# Geometry: Planning the last 6 weeks

The last six weeks of geometry will focus on similarity, dilatation, indirect measurement, similarity transformation proofs, and circles: We will start with a review of real world ratio and proportion practice, interactive notes page & review, possible including activities such as New York Minute (NCTM Illuminations). We will then head into applying the properties of proportion … Continue reading Geometry: Planning the last 6 weeks
