In another life, I was worried my students would be short-changed if they weren’t exposed to graphing calculators. I went to exorbitant lengths both to learn how to use a graphing calculator and locate appropriate labs and activities. I went to several conferences and bought videos. Even now, I incorporate graphing exercises into my science classes. I keep a set of graphing calculators. My husband, Rob, teaches Math for the local Co-op. He loathes the graphing calculators; I help his kids with graphing exercises in Algebra or Stats, too. My advice is to Google the graphing problem specifically. Type of exact problem into the search. Sometimes the video explains exactly how to calculate or input the problem. I usually prefer the screenshots to videos. Ironically, I’m sharing a few videos I made for the kids. Rob maintains a video library in Google Classroom.
Here is how to clear the RAM. I suggest clearing the RAM on the graphing calculator before starting a new exercise. Sometimes an equation in y=, data in the STAT function, or a matrix can cause havoc. Here is how to clear the RAM.
Below is a video of how to input a linear regression, one of the most common types of exercises.
Here is a video about graphing inequalities.
