Similar Polygon Exploration in Geogebra

Use Geogebra to create similar polygons, compare the scale factor of a dilation with the side lengths of the image and preimage compare the scale factor with the ratio of the perimeters compare the scale factor with the ratio of the areas A written version of the investigation is below. Similar Polygon Exploration To see [...]

Congruent Triangles Unit

Classifying Triangles Again, I'm re-creating the wheel, hoping to make it better. My students responded well to the doodle notes I created for my Transformations Unit. One commented, "I'm really understanding the material now. Honestly, your class was a little boring, but this chapter was much better." It's amazing how turning the tables on students [...]

Sequences, Series, & Probability

Based on feedback from my geometry students, I've created some doodle notes for my pre-calculus classes as well. Sequences and Series This notes sheet can be used to help explain the the vocabulary involved withe sequences and series - explicit, recursive, summation, factorial, etc. It helps prepare students for Arithmetic and Geometric Sequences. Arithmetic Sequences [...]

Transformations Unit

Translations As an informal assessment, I gave my students a Halloween Transformations worksheet to a) keep them off their phones after they finished their chapter tests and b) see how much they remember about or can do regarding transformations with minimal instruction. Most completed the assignment with no issues. Translations Doodle Notes can help students [...]

The Challenges of Using Technology

One of my unspoken goals for this year has been to include more explorations in my Geometry classes - specifically Geogebra explorations. This has posed some challenges. The iPad cart I have been checking out has 20 devices and I have had up to 30 students in my classes. Compensation: pair students up. It makes [...]

Parallel and Perpendicular Lines

Types of Lines While parallel and perpendicular lines will be the primary focus of this chapter, there are other types of lines. Use the Types of Lines Foldable to distinguish between them. Types of Angles When two lines are cut by a transversal, there are special names for the angles formed by the transversal and the lines. [...]
