Here is the interactive notebook page I created for my Algebra 2 students over solving quadratics by factoring. I typed up the Zero-Product Property for students to cut out and glue in their notebooks.
In the future, I’d probably type up the steps as well to save time. I might make them fill in the blank or something similar…

My 2015 notes for this topic looked very similar.
I used these same two equations in my notes for solving quadratics by graphing to make the connection between the two methods.

Hmm, the pic showed after posting the above comment so I am going to try again for the others!

Your picture is not showing here and I would LOVE to see what you had originally displayed. I decided late (after school started) to implement the INB. I figure any help I can give my current students to best understand is better than waiting until next semester for the new group of students. (We are on the 4X4 block.) Any suggestions for a late starter would be appreciated! I LOVE YOUR WORK!!!

I would like to conduct an action research to test the effectiveness of INB,to my own students. Can you please help me for some conceptual framework?

I'm not sure exactly what you're asking for. Could you be more specific?

Here in the Philippines we use the same term. But do you have action research sample Ms. Sarah?

I don't. I'm hoping to perform my own research project on INBs, though. I will hopefully post about it once I start the process. :)
