## 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 Vizual 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 Vizual Notes can help students [...]

## A Tale of Three Classes

Two weeks ago I wrote a post called Equations from Data. In it, my pre-calculus students first were charged with finding a curve of best fit for global iPod sales data from 2006 to the present. Then they were asked to find an equation for the curve of best fit for global iPhone sales. The goal was to show [...]

## 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. [...]

## Equations from Data

When businesses, governments and other policy makers prepare to make decisions, they often look at data to find trends. In this activity, we will use data and a graphing calculator, Desmos, or Geogebra to find an equation that best fits the data points. Statista has Global Apple iPod sales (in million units). Plot the data [...]
