Over the past week we've been taking notes on slope and slope intercept form. Below are pictures from our class interactive notebook that is maintained. Students have their own individual copies.
Credit for all of these pages comes from Sarah Hagan at Math ='s Love. She is a teacher in OK and maintains an amazing blog full of notes and ideas.
Sarah's blog introduced me to Slope Dude. I told the kids, his video may change your lives forever.
The below notes will make sense after watching the video!
We then talked about Rate of Change some more. This was an extension of our conversations over the past couple of weeks for the Walk-A-Thon and Walk-This-Way activities.
Several students told me that delta was a greek sign or a military call signal and we had to talk about the mathematical significance as well. Prior connections right?
Then we talked about how to find slope from a graph. Every time I made them say whatever Slope Dude would say :)
Next was finding slope from a table or points. At this point, they should have examples for how to find slope from a table, graph, and points and therefore be able to find the slope from various formats!
X and Y intercepts followed slope. This caused a little bit of frustration. The following page shows two examples that were walked through. The kids were given points to graph, determine slope, x & y intercepts for four remaining examples.
Last but not least was Slope Intercept Form.
This is one topic I always struggled with and have loved how the notes lay everything out for you!
From here they had a worksheet to practice!
Side note - I only have one class interactive notebook but create new pages on loose leaf paper for each class period after the initial entry into the class notebook. This allows me to give notes to students who were missing if needed. Also the tabs on the right in the above picture allow me to know where I get to for each class period!
