Dear software developers - you may have 100s of features, great customer service, gorgeous graphics and an amazing interface, but without a quality EQUATION EDITOR you are severely lacking fundamental functionality for my students. Sincerely, Disgruntled Math Teacher #iteachmath
So after I spent weeks carefully planning to use breakouts to give students meaningful interactions with me and each other my district tells us today that to conserve bandwidth we can only have 1 meet going and in-class students can't join it. COOL #iteachmath #hybridlearning
I am at that point in my anxiety over starting hybrid teaching in a few weeks that I’m thankful to have so many college recs to write. At least I can feel productive and not completely lost for part of the day #iteachmath
Has anyone used slack in the classroom? If so, how'd it go? My district wants us to stick with google meet pretty exclusively to limit platforms students need to learn, but I think my high school students are probably pretty adept at learning these things. #MTBoS #iteachmath
I’ve heard of chair yoga but what I really need is yoga I can do beside my toddler’s crib when I’m negotiating to get her out of it. #toddler #iteachmath
I've found that teaching function transformations works best when I let students both put pen to page and experiment on @Desmos. Having the online activity google.com/url?q=https%3A… and a physical packet drive.google.com/file/d/13u4t2l… lets students see different ways #MTBoS #Iteachmath
need some advice from the #MTBoS and particularly #precalc teachers. In my district the honors course for juniors is a packed-to-the-brim combo of algebra 2/trig and precalc. Descartes Rule of Signs or using sum/product for higher degree polynomials, which goes? #iteachmath
Related: what about the fact that the magnitude of the cross product of two vectors has the same numerical value as the area of the implied parallelogram? To borrow from JS a bit, I think it depends whether you think of “the same” as something like “==“ vs “===“

I wrote a post on why I love one of my day 1 problems for an honors algebra 2/precalc course. It's a simple problem but I think it sets the right tone. Curious if anyone in the #MTBoS has similar attachment to an easy first problem. pmmath.com/tangential-tho… #iteachmath
Trying to use @Desmos to try to make an esoteric concept - formal concept of a limit - a but more tangible. I came up with this: pmmath.com/desmos-demos/ also made a video (linked in site) using the activity. soliciting feedback from #MTBoS #iteachmath
I firmly believe all math curricula should dedicate a full year to nothing but Martin Gardner puzzles.
Really having a lot of fun playing with the new stat features in @Desmos. Really wish I had these before coming up with this though... desmos.com/calculator/cyr… #Statistics #mathteacher
