How to Guide: Using Sliders with Desmos Graphing Calculator
This How to Guide is about how to use the sliders feature in Desmos. This focuses on recognizing form in an equation, systems, circles, and function notation with how to interpret the visuals that Desmos can create. Tips and previews of the output are provided to guide the thinking and understanding behind answering more abstract questions. There are practice prompts provided at the end.

How To Guide: Using the Desmos Graphing Calculator
I created this How to Guide with examples and descriptions with methods of using the free, online Desmos graphing calculator. Learning how to use this tool will lead to being an effective problem solver and standardized test taker. The goal is to allow students to connect to both algebraic and graphical representations of solutions. This also shares how to utilize the table feature for both testing points and analyzing statistical data from a table.

Introduction to Unit Circle Notes
Creating circle and right triangle diagrams via Desmos, I used this resource to allow students to connect their understanding of the coordinate plane and special right triangles to develop connections to angle sketches and how they relate to their terminal sides intersecting as points on the unit circle.

Reference Summary of Exponential & Logarithmic Graphs
This was used after an Amplify Investigation of Exponential and Logarithmic graphs. I always have students summarize findings in one place to use as a reference sheet as we continue to practice the skills. Two interconnected examples are provided to synthesize the idea of inverses both algebraically and graphically.

Polynomial Long Division: Detailed Example with Structure
I created this layout as a tool to give a detailed breakdown of Long Division with Polynomials for students to reference as they work through this topic. I would utilize this as notes to lead into more challenging examples. This allows students to see the cyclical pattern of steps as well as to see the polynomial arithmetic involved along the way. This is a great tool for an in-class support Algebra 2 course. I would highly suggest teaching with color coordination that students can mimic at

Summary of Derivative Rules
I compiled this graphic organizer so students can compare and contrast when to use which derivative rule - power, product, quotient, chain, and a mix of multiple. Many students forget to simplify the original expression to use one rule that is more direct over another, so I designed the problems to have students reflect on that piece as well. This serves as a good summary and includes various function types.

Reference Sheet of Complex Numbers & Quadratics
This reference sheet could be used leading up to an assessment as a review guide OR as a summary and revisit post assessment. I printed this out for my students on colored paper emphasizing that all the skills of using Complex Numbers and Solving Quadratic functions will be utilized when working with Higher Order Polynomials next unit, and beyond. Having a reference sheet with processes and examples allows students to hone in on the crucial skills built on throughout Algebra 2.

Recall Activity: Circle Vocabulary
This activity highlights key circle vocabulary and allows students to create their own color coordinated diagrams to represent their understanding of these terms. By using the shape tools and text boxes in Easel, students can make clear, organized diagrams to demonstrate their familiarity with the vocabulary, how to sketch an appropriate diagram, and use proper naming notation. This could also be used as an introduction to circles in Geometry to gather prerequisite knowledge and foster discus

Warm Up: Connecting to Signs of Six Trig. Ratios in Quadrants
This is a Warm Up to allow students to connect to the signs of the six trigonometric ratios before formally learning the Unit Circle. Students will be asked to sketch angles in both radians and degrees in 3 of the four quadrants, excluding quadrant 1. Then, they are finding combinations of the six trig. ratios using the reference angle triangle and special right triangle ratios. At the end, students are asked to generalize the signs of the trig. ratios in each quadrant. *NOTE: I use "Always

Inspirational Poster: Grit & Attitude for Math & Future Success
I created this mini poster to get students to think about how Grit and Attitude can impact their success in both the mathematics classroom as well as their futures. When students continuously question why they are learning skills in math class, I find a key response is their ability to problem solve, react to setbacks, and continue to persevere through challenges that support growth!
