Get Squared Away

The Leaning Tower of Pisa is famous for it's tilt. The question is: how close is the tower to falling? This investigation takes students through answering this question. This uses a Geogebra applet I created (a website link is provided) so students will need access to a computer per student or group of students. This activity allows students to compare the ratio of height over base at different angle measures to estimate the angle the tower is currently leaning. This ratio is our tangent ratio a

This guided notes set introduces the quadratic formula with guided practice and independent practice problems for students to complete. The top section provides a mini-lesson over the quadratic formula and it's parts (determinant, etc.). This notes set is modelled after the "I do, we do, you do" format. There is a class example, a couple of guided examples, and multiple extra practice problems that get more difficult as the worksheet progresses. The last couple of problems ask students to come u

This scale factors exploration activity leads students through the process of discovering the relationship between scale factors of length, area, volume. One example problem is included that shows how this relationship can simplify calculations that previously took multiple steps (work is shown to demonstrate both methods of solving the problem). Answer key included. This activity goes along with Ohio Geometry Standard G.GMD.6.

This editable lesson plan over spheres (vocabulary, surface area, and volume) covers each of the categories in the OTES teacher rating rubric. The lesson plan includes standards, prior and future learning, learning targets, and more. Looking for more resources on spheres such as guided notes, presentation slides, and practice activities?

Introduction to Circles Unit: Circles Guided Notes- This two page set of notes covers the basics about circles vocabulary you lead into your circles unit in Geometry. Complete with diagrams, fill in the blank definitions and formulas, and example problems for the students to work on after the notes. The practice problems are in a multiple choice format. Two answer keys are included (one with example answers not given (for teaching purposes) and one with all correct answers marked). Looking for
