#iTeachMath Teaching Precalc to kids who will go to AP Calc next year. What does college board expect in terms of limits near vertical asymptotes? DNE, limit is infinity, either/both?

They keep saying AI will free up time for teachers by streamlining meaningless tasks. “Gemini, sort these 26 sets of papers that I collated by mistake into separate piles.” That saved me all kinds of time!

#iTeachMath Showed freshmen today how to put square roots in simplest radical form. Them asked them about a cube root, and higher roots. They were astounded! “This is REVOLUTIONIZING!” Sometimes kids are awesome.

#iTeachMath Is there a valid reason for having students know the coordinates of the special angles on the Unit Circle? Is it sufficient for them to just know the ratios of the sides?

Can we get a podcast of women rolling their eyes at the stupid things men do and say? Yes, a podcast. You can record it for video as well, but the eye rolling would be so loud…

We asked teachers what they think about reforms meant to save them time. Their verdict? Most of the "fixes" might actually create more work. Here's what they told us: kappanonline.org/time-well-sp... @jackschneider.bsky.social

Teacher are too often overwhelmed with things to do. What reforms do they believe will be most effective in helping them manage their time?

#iteachmath #mtbos What do you call it when you solve a log equation by performing the operation of making, say, 10 the base of each side? log(x+2) = 5 10^log(x+2) = 10^5 What’s the name of this operation?

Teaching precalc to kids who might take AP Calc next year and running up against winter break. Is Descartes’ Rule of Signs vital, or a nice little curiosity in these modern times? If I leave it out, my life will be better. Will theirs?

Asking on the 6th/7th of December: How’s the 6,7 thing going now? I heard it once, jokingly, from a senior this week. The younger kids seem to have let it die off. Like bottle flipping and killer clowns and fidget spinners. This, too, has passed.

I have a student who is VERY bright but always tries to game the system, looking for a work-around or a shortcut, often successfully. Yesterday, explaining his thinking: Now I look for this thing I like to call “The Number That Will Get Us The Answer.” I say, “We like to call that x.” 🤔🤗🤣
