Ok, so this is no Khan Academy, but it’s still pretty exciting that I can record videos: I used ActivInspire’s screen recorder and a slate. Large classes and ill-prepared students mean I need to get my kids to a more self-sufficient place. I hope this helps.

This project was totally cribbed from someone else. Unfortunately, I cannot find the original link. I rewrote it and am kinda proud of the standards-based rubric at the end. Using the metaphor of functions grouped into families, I ask students to create a scrapbook showing all the family members (function transformations) and describing them (characteristics). [...]
A carpenter’s measuring tricks fascinate me. These guys have figured out ways to do math without all that pesky math getting in the way. The most recent trick I learned is a great geometry class problem: how to divide anything into equally-sized sections. For example, suppose I want to place the handles exactly 1/4 the [...]
Next up with my ninth grade math class: solving rational equations. I’ve been having fun with combined rate problems such as, “How long does it take Timmy and Marsha to mow the grass if it takes Timmy 2 hours on his own and Marsha 1.5 hours on her own?” I, therefore, with great pride present [...]
Electrical circuits is the one area in engineering school I completely sucked at because I had a knack for letting out the magic smoke of many a project. Well, I’m back at it. Hopefully, I’m a bit more knowledgeable now & I’m definitely staying away from capacitors. I have here a pretty cool project cribbed [...]
I really don’t like going this deep inside the box to think…but my kids have to prepare for major standardized tests. With that caveat, I now present resources I like to prep students for the End of Course Test after Math 1 (9th grade math – algebra, geometry, & statistics). First up: I like the [...]
Get 4 rounds of Probability Trivia (PowerPoint | PDF). Set your Adobe Reader to scroll (View menu > Automatically Scroll or Shift + Ctrl + H). Put on music the kids might actually like. Then roam the room to help kids who struggle. I’m not much at expounding, but if I had to list the [...]
Recently spotted on the Duarte Blog: Cheating by Charting. An excerpt from Spear’s Practical Charting Techniques. This stuff is genius. Methinks this could be used in math class. “Hey kids, we’re going to play Corporate Spin today. You’ll hide a disappointing stat in a graph so the public doesn’t realize how much we’re polluting/raising prices/whatever.” [...]
What time of day was this photo of the Washington Monument taken? While writing this warm-up question, I came across the Sun or Moon Altitude/Azimuth Table page. Supply a location and a date and this page will tell you the angle of sun in the sky for any time of day. (Interesting side note: This [...]
(Props to my colleague Annie Sun for the idea for this game) The goal is to get as close to 21 + 21i without going over. Georgia Performance Standard MM2N1(b,c)
