I have created a course based off of Desmos activities. The course provides supplementary once-a-week content to the Introduction to College Math course at Nevada State College. The outline of the course is below.
Students should bring laptops or tablets to every class. They can work in pairs, but they will need a computer.
Prior to each class period you will create each activity using your account at teacher.desmos.com. Send students to student.desmos.com, and have them enter the codes you give them for each activity. These exercises are supposed to be exploratory in nature. Students will learn how Desmos can help them to answer their questions and they will become comfortable learning math and expressing their answers.
Note that students must create their own Desmos account if they want to save their work for future use.
