Thinking about the kiddo who came in who hadn’t had math in 10 years… time to make this thing happen and get a degree… who surmised that 76/80 was 96 percent because   60/80 was 75 percent. Stopped math after sophomore year but “yea, I was good at it, people asked me for help.” It […]

I really do oft reflect happily about our Math courses being taught for understanding, and speculate that I’d find another job if they weren’t.

Still, I wanted to feature Casey/Gravity 🙂   It behaved rather oddly — the greater than text layer switched to a mirror image of itself… then the dogs switched… I’ve observed with things visual or mechanical that my first attempts […]

I have two images I want to make ASAP — the meta-goal being to learn to make images efficiently. For “bar model” of percents… for purposes of OER … having puzzle pieces seems to be a way to go. Same with number lines. I started making one big image of a whole and then the […]
