My wonderful husband got me a whiteboard for Christmas so that I could start making math teaching videos. After taking a few days to get everything set up, all the while wondering where to start, I decided to work my way through my math cheat sheets and make companion videos, starting with Algebra 2.
In this post is a video example of graphing quadratic functions in vertex form, a link to a free math reference sheet to go along with the video, and a link to a free vertex form quadratics task card activity.
Towards the end of the video is a shortcut for graphing vertex form quadratics with a pattern instead of a table.
Quick story: When I made the switch from my desk job to teaching, I was subbing in the Boston Public Schools and also interning with a video production company. The internship was unpaid, so I made the deal to take the first job that opened-- full-time teaching or paid video editing. Teaching opened up first and the rest is history. This kept my parents happy, too. Still, I always missed the creativity that came with editing videos. Math is creative too, but you know what I mean. So I am excited to combine the two by editing math videos. It's been a bit, so I'm rusty! But I'm excited for the challenge.

My hope is that you will be able to use my videos as a supplement in your classroom on a sub day, in a flipped classroom for kids to watch at home, or as a way to bring algebra 2 to your homeschool classroom.
Below you'll find links to the video, a free math cheat sheet on graphing quadratic functions in vertex form and a free pdf task cards activity.

Here's a super short video showing how to graph a quadratic in vertex form:
And one made with cut paper:
Here's a longer video with more explanation. Towards the end of the video is a cool pattern that arises when graphing vertex form quadratics:
Super cool!!! I'm always looking for videos for my higher kids. BTW, we have vertex form in Algebra 1.
ReplyDeleteAND - So fun to see and hear you!
I always forget how similar algebra 1 and 2 are these days! Thank you for reminding me. Can you tell I was a little nervous? Back in the day I was only ever behind the camera. But I'll work on it! I hope you have a wonderful weekend!
DeleteJust ordered several bundles of your work for my Math7 and Algebra 2 students!! The quality is exceptional. I am excited to see how my students will embrace them. We are still in remote learning mode so I am always looking for ways to engage them.
ReplyDeleteThank you so much! I really appreciate that. If you find yourself needing any activities to complete the bundles, I'd love hearing from you. shana@scaffoldedmath.com
DeleteThis is a great activity that I'm excited to use. Thank you! One question: what does it mean on your sheet: Inside + Right, Inside - Left, Outside + Up, Outside - Down?
ReplyDeleteJust a quick edit...Inside - Right, Inside + Left. This is a cheat for remembering that addition inside the (parenthesis) will send the vertex left (and subtraction inside the ( ) will send the vertex right). This is because we're looking for the value of x inside the ( ) that will make that ( )^2 = 0.
ReplyDeleteFor example, if we have (x - 4)^2, x = +4 to make ( )^2 = 0. So x is a +, sending it right on the coordinate plane.
