The Rolling Cups task from the Shell Center is a perfect geometry modeling project. I use some form of this task every year for the last three days of the first semester as a final project. This task incorporates constructions, similarity, functions and modeling while pre-assessing students readiness for next semester's content: solids and circles. … Continue reading Rolling Cups: Modeling in Geometry

Click here to access and comment on the Geometry Planning guide Units: Constructions Congruence Transformations & Similarity Right triangles & Coordinate Proof Applied Trigonometry & Solids Circles In the spirit of Geoff Krall's Problem Based Curriculum Maps, I attempted to organize my geometry curriculum and learning targets along with associated activities, tasks & lessons. In order … Continue reading Geometry Planning Guide

# Sprinkler System Design

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

# Squares, Area & The Pythagorean theorem

After a few days working on surface area, I wanted to challenge my students and address the standard listed below by with a task that applied area in a different context. I debated about using this task because I couldn't envision how I would engage students and encourage them to persist in proving that a … Continue reading Squares, Area & The Pythagorean theorem

# My “Explore The MTBoS” Homework

I have been avoiding posting because I feel like I have to share THE BEST open ended problem. I am positive that about 2 hours after writing this post, I'll think of one that I like better, and I'll be mad at myself. But I said that I would do this, so I'm doing this! … Continue reading My “Explore The MTBoS” Homework
