## Increasing Engagement

I remember being frustrated last year at about this time with my geometry students' performance on four questions on their circles test. The test was chronologically ordered in the way the material was presented so I was perplexed when they did poorly on the last section before review. It involved circles in the coordinate plane. Below are [...]

## Polar Coordinates and Graphs

I remember being frightened by the polar coordinate system and graphing equations using it when I was in my students' seats many years ago. With graphing calculators, this doesn't have to be intimidating. I started the unit with an introduction to the polar coordinate system and reminded my students about how intimately familiar they are [...]

## Sine, Cosine, and Tangent Ratios

Spring break brought out the creative juices. I spent time reworking guided notes sheets from last year into doodle notes this year. I like how they turned out. The Tangent Ratio Sine and Cosine Ratios I love it when I can start the class with a real world problem and help them arrive at a [...]

## Conics!

It's conic section time in Pre-Calculus. Learning from last year, I added a section on circles. I polled my students prior to spring break and they didn't recall the equation of a circle in standard form. To dust off the rust and get into completing the square mode, I created some doodle notes and a [...]

## 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 https://youtu.be/S2orPH6CqLk A written version of the investigation is below. Similar Polygon Exploration To see [...]

## Crack the Code

As a review for the semester 1 final, I created a review centered around deciphering clues. My students are not always good about doing work accurately. Some want to just write down an answer to finish. This several day long activity is designed to promote accuracy. There are several parts.           [...]

## 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 [...]
