Calling all teachers to help me make these better!
This summer at Twitter Math Camp, Glenn (@gwaddellnvhs) and Jonathan (@rawrdimus) showed us how they lead students through all of the functions in Algebra 2. Basically, they put all of the equations into (h,k) form. Fortunately, the book I am using this year, “Discovering Advanced Algebra” does basically the same thing. Since it is a “discovery” book, they have some good ideas that I have been able to modify and made into INB (Interactive Notebook) form. Never fear, this just means it’s a worksheet that you fold in half.
The first discovery was also my students first introduction to graphing with Desmos on their own. Of course they have seen me use Desmos multiple times by now since Desmos has all of those great example graphs in their side bar!
Here is how I progressed through discovery for linears, quadratics, square root, and absolute value. The Box files with the word docs are at the end.
- Horizontal and Vertical Shifts
- Reflections with the square root function
- Dilations with the absolute value function – these last two are combined into one. I would love any suggestions on this – before Monday. I know, I’m asking for too much here! 🙂
Also included is a “Transformations Parent Graph” foldable that I made to sum it up. I kind of hate this one, and would love suggestions here for sure! Should I add dilations? Why is it so ugly? What else do I need to add? I need help here for sure.
Please note: I did not make all of these discoveries from “scratch”. I created some of them. But some were inspired by the textbook I am using this year, “Discovering Advanced Algebra” and some were created by my amazing co-teacher. I then adapted all of them for INB (Interactive Notebook) form.
