I made some final tweaks to Completing the Square in Algebra 2, and I find it just amazing the difference between this year and previous years, in that so much more often now, I just know what to do. It doesn't feel like I changed all that much, but the kids just get it. I don't think it's a difference in delivery or anything. Here are the important bits. First, I took two days instead of one. Go to hell, pacing calendar. The first day is just to see the pattern and get the idea with easy…

An interesting post comparing polynomial division methods on the More Than a Geek blog reminded me of my own experience teaching completing the sqaure. There were times in my career where I absolu…

Yesterday I ahem-ed and winked to my Algebra II class about them needing to know how to complete the square for class today. Teaching this topic last year was a nightmare. A total trainwreck. Stude…

There seems to be some interest in how to use algebra tiles in the MTBoS so I thought I would attempt a blog post. I apologize now if I confuse anyone - I don't claim to be an expert, but I do find they help kids make connections. For years I avoided algebra tiles. It didn't help that one of my previous colleagues told the story of how one of her students managed to choke on a tile! Thankfully, none of my students have done that. Our tiles are red and blue so they all feel the need to look…

Alberta Curriculum: 20-1 Relations and Functions This lesson addresses the process for "Completing the Square" in order to address the following outcome: *Analyze quadratic functions of the form y=ax^2+bx+c to identify characteristics of the corresponding graph, including vertex, domain and rang...
