As this schoolhouse yr starts to come upwards to a close, I'm reflecting on what worked as well as what didn't work. Yes, I realize it's alone the start of March. We haven't fifty-fifty had Spring Break yet. But, I've woken upwards to the realization that I convey twenty schoolhouse days left amongst my students earlier end-of-instruction testing begins. 20 days. 20 days! I did this counting on Fri when our counselor e-mailed out the standardized testing schedule. I pulled out my calendar as well as counted. 23 days. Then, nosotros had
two snowfall days. Awesome.
I'm currently working on a excogitation to figure out how to necktie upwards all the lose ends earlier testing. My Algebra 2 students convey yet to produce polynomial long division, solving rational equations, composition of functions, or operations amongst functions. My Algebra 1 students withal necessitate to larn solving systems past times substitution, solving systems past times elimination, graphing linear inequalities, graphing absolute value graphs, as well as simplifying radicals. My, oh my! It is going to travel a sprint to the finish!
You could tell I'm inward panic mode. Want to run across where my priorities are, y'all? I'm fifty-fifty to a greater extent than panicked than I felt when I saw this a few weeks ago. There's nix similar a
conic cards!)
Here's how I modeled it on my SMART Board.

Here are the names of the forms. Here are the formulas. What produce you notice? How tin flame you tell them apart? Vertex shape has parentheses. Doesn't intercept shape convey parentheses, too? The parentheses inward vertex shape convey an exponent of two. Now, we're getting somewhere. Intercept shape volition e'er convey 2 sets of parentheses. Will it? Are you sure? They continued throwing out ideas on how to tell the dissimilar forms apart. I'm kinda glad I had them convey this conversation every bit a flat earlier nosotros ever started trying to split upwards quadratics past times their form.

We played 1 of my favorite games for classifying stuff. The Flyswatter Game!

Two teams. Throw a moving painting of a component subdivision on the SMART Board. First thespian to correctly swat the right shape on the dry out erase board gets to remain inward the game. Other thespian has to sit down down. Two novel players become to the board. Another function. Another showdown. Winner stays inward the game. Loser sits. Game continues until alone 1 squad is left.

Practice, practice, practice. I made a slight alter to the flyswatter game this fourth dimension around, though. I had students who weren't playing at the fourth dimension remain inward their seats. They used their notebooks to create upwards one's hear the form. Students at the board had to create upwards one's hear the shape without their notebooks. Students amongst notebooks "graded" the piece of job of the students at the board.
The best component subdivision of the game was hearing students explicate to other students why their classification was wrong. "But, it can't travel inward measure form. It has parentheses. Standard shape volition never convey parentheses." Students teaching students. Win!
On Day 2, nosotros went dorsum to our foldables. We added inward instructions on how to graph quadratics depending on their forms. This foldable, past times the way, is made from a unmarried canvas of newspaper that has been cutting inward one-half hamburger/taco style. Lay the 2 layers of newspaper on transcend of each other. Scoot the transcend layer upwards an inch or so. Bring the transcend of the newspaper downwards to bottom of the newspaper to create 4 flaps. Staple. Take notes. Enjoy.

The bottom of each department contains of import data nigh the equation as well as its graph. The transcend of each flap contains an example.

After nosotros created this foldable, nosotros went dorsum to the functions from the flyswatter game. Again, nosotros would create upwards one's hear the form. But, this fourth dimension nosotros had the necessary tools to graph the function. We graphed the functions on mini dry out erase boards, as well as students held upwards their boards to travel checked.
Next year, I desire to ready out to brand this fifty-fifty better. Ideas? Do you explicitly learn the dissimilar forms of a quadratic function? I'd honey to hear from you inward the comments!
