Lesson 1.7: Multiple Representations of Linear Patterns These slides correlate to my handout for 1.7. There is no slide for #1, since #1 is intended to be worked by students, not presented by the teacher (students can present their solutions at the document camera or whiteboard). #2 is intended to be presented by the teacher in discussion with the students. #3 is for students to practice (the slide is just to display the answer after students have worked on it). #4, 5, and 6 are also for students to practice on their own, with the slide displaying the answers after they’ve had a chance to work. Of course, you can do whatever you’d like—that’s just how I use these materials.
