Generally when I teach factoring I teach all quadratic trinomials in one class period, but this year I had so many struggling learners that I realized I needed to break it up a little more. So I wrote two circuits, one with c > 0 and this one with c < 0. I am posting this one for free so you can help your struggling learners master this important skill too.
The way the circuit works, the student starts in the first "cell" and factors that trinomial. Then, to advance in the circuit, the student must find ONE of the factors. (There will only be one available.) If the student does everything correctly, the circuit will close by coming back to the beginning. If the student makes a mistake, then that opens up a chance for great dialog with the table partner, the teacher, the group, the special education resource teacher, etc.
The teacher needs to download the circuit first and work it to understand the progression through the skill. I do not include an answer key because the answers are embedded in the circuit. Then, give your students a few examples or even begin to work the circuit with them as guided notes. The students will dig in and take care of the rest!
If you like the circuit, I have MANY circuits on factoring and they can be downloaded individually or as a bundle, Here is the link to the bundle. (You may need to copy and paste it.) It also includes a matching activity.
