Quadratic Formula Templates

This week, my Algebra 2 students started solving quadratics using the quadratic formula. Wednesday, I passed out i of my favorite homework assignments of the yr to acquire them started off right.

This year, I didn't learn it to them to the melody of quadratic formula. Instead, I gave them the paper, allow them freak out a chip in addition to elbow grease to memorize it on their own. A few students remembered their older siblings singing the vocal in addition to filled the residuum of the flat inward on how it went. That was fun to see. :) I likewise told them to cheque out YouTube to notice a version of the vocal that would assistance them recall it.

Yesterday, I knew I wanted to do a notes template that would assistance them organize their work. In the past, I've done a Tangram Puzzle for them to cutting in addition to glue inward their notebooks.

This was cute, but my I institute my students need H5N1 LOT to a greater extent than assistance amongst setting upward the problems than I bring given inward the past. So, I whipped upward this template on my planning period:

I inserted it into a quick booklet foldable amongst ii illustration problems for my students to piece of work through.

My students seemed to empathise where the a, b, in addition to c came from much easier amongst this template. Of course, they freaked out a chip when the imaginary numbers came into play...

After working through the do problems, I laid each grouping upward amongst a Quadratic Formula Question Stack Activity. The cards I operate are hand-written because I made them final yr earlier I had a calculator template, in addition to therefore I don't bring a laid to share. Sorry! (But, you lot tin larn to a greater extent than close Question Stacks here.)

I decided at the final infinitesimal that I should brand them a dry out erase template to assistance gear upward each problem. I only cutting in addition to pasted the template from the notes onto a blank document in addition to increased the font.

They weren't pretty, but they worked. We slid them into these dry out erase pockets to brand them erasable in addition to reusable.

The kids insisted nosotros locomote out the red/yellow/green cups in addition to therefore they could dot when their grouping was having trouble. The matter that I liked the best from this was that when a grouping was having problems, it was super tardily for me to figure out if they had fifty-fifty gear upward their work correctly since that's where I notice most errors occur when working amongst the quadratic formula.

I tweeted a movie from this lesson, in addition to John Golden suggested using unlike shapes for a, b, in addition to c.

Of course, I had to pretty-up my dry out erase template for the future, in addition to therefore I created ii versions.

Version 1: Regular Rectangles

Version 2: Different Shapes
