Project #1: Desmos project – due September 7

Project #1 consists of two components: an oral presentations and an OpenLab post. The project must be completed individually, but you are encouraged to discuss with your fellow classmates.

Instructions:

1. Select a standard from the New York State Common Core Learning Standards for math or another math topic of your choosing. (Some sample topics are listed below.) Each student’s topic must be different; inform the instructor of your choice.
2. Use Desmos to create an introductory activity or motivating example for this topic. (Create a free account so you can save your work.)
3. Prepare a 10-minute lesson that you will present to the class.
4. Create a post on your own EPortfolio briefly summarizing the lesson. (See the sample here.) Explain how you used Desmos and what features you used. Include links and/or screenshots. Let us know who the intended audience is for your lesson and what math content knowledge you are assuming they have. Title your post: “Project #1 – [your topic].”

Due date: Thursday, September 7
OpenLab post due before class. Presentations in class.

Sample topic ideas:

• The definition of the derivative: the tangent as a limit of secant lines
• Riemann sums and definite integrals
• Transformations of functions and their graphs
• Inverse functions and their graphs
• The definition of trigonometric functions using the unit circle
• Solving inequalities
• Regression: lines and curves of best fit
• Graphs of linear functions: changing slopes and -intercepts

Sample Desmos activity

Feedback:
On September 7, there will be 2-3 minutes between presentations. During this time, you will submit feedback for your classmates’ presentations using this form.
