@Mrs_CHibbard @mathillustrated @librarycongress 4th grade circa 67/68 (Catholic school) the "new way" was called long division, then we learned the other way

@mathillustrated @librarycongress I can vouch for the new way being taught in 68 and 69 in my elementary, then moving to a different school and learning the old way. I was confused until Grandma helped me.

I've learned that this "new way" of doing long division has been called "new" since at least... 1706. Research at @librarycongress 😃 #iTeachMath #EinsteinFellows24 #math #education

@abel_jennifer Hexaglexagons were a hit; check out vi hart videos, we did occasional mini lessons on fun historical problems: hilberts hotel; 4 color map problem, etc

I had 38 high schoolers show up to play 24 today during a math club meeting! What else can I do that would be fun? #MTBoS #iTeachMath

@untilnextstop Just an observation from my experiences. Many "mathy" kids do better with poetry where there are rules... Limericks, haiku, alliteration. It imposes structure that makes it more comfortable to write

@KT_is_Reading @JayWamsted From a high school teacher, a clock on the wall or a teacher periodically writing the actual time on the board was helpful to many kids, but a countdown timer completely stressed out a significant number of them. Took them off everything.

@JayWamsted And yet, every standardized test (that I’ve proctored) requires a clock to be visible.

One of my children kept bombing out on their multiplication tests, those one minute timed monsters We took the visible timer away and they aced it, still coming in way under time Just think about that for a moment. It was the sight of the timer that was the problem

@anniek_p The day you sign up for that subscription is the day they start refusing all bananas

@untilnextstop I don't know what it is called either, but always used it as an example in pre-calc. The eccentricity---the place where an ellipses switches to a hyperbola

@mathequalslove We played that every year. Did 2v2 couldn't finish a full game in 45 minutes, but it cemented 4 names for each point and allowed a lot of fun trash talking

Played Polar Coordinate Battleship at the AP Precalculus APSI I'm attending today. Very fun! I look forward to adapting this for my students this year. #mtbos #iteachmath #APPrecalculus #precalchat #precalcchat

@Trianglemancsd Seems to me she successfully managed to "sit in a chair that is too small" and appropriately applauded. How fun

@misscalcul8 Not the most obvious path, and a few notational errors, but every step is legal. I'd give full credit.

@IanKerr_math If you need inspiration, check out this book.

If I'm ever looking for a tattoo, I might go here just on principle. #mtbos

@untilnextstop Have you played ravensburger's labyrinth

@bowmanimal I'd second set, but may need to be more cooperative than competitive. Also tiny polka dots is good for under six, War works as math and blokus if cooperative game

@bowmanimal That's more than a small victory

@bobloch @Desmos @GrittyNHL It's awesome, but poor Gritty doesn't even have a stick

This year I introduced an animation project to my 9th graders using @Desmos. Lots of nifty submissions this first time around. First, @GrittyNHL as goalkeeper (1/3)

@misscalcul8 Is he assuming the diagonals bisect the vertex angles? SAS usually works with law of cosine.

@untilnextstop @druinok JoAnns has a decent yarn selection. Yarn comes in different weights,( thickness). The hook size goes with yarn weight usually- the yarn wrapper will suggest a good hook size to use and your pattern usually tells you yarn weight and hook size

@lethalpaints @misterdiehl Alternatively providing an explanation

@misterdiehl this implies you were asking permission to try ayahuasca

I gave a similar speech to my mom at age 16, didn't work

@Mrs_Meowmerz @theonides a/x and b/x^2 (typo)

@Mrs_Meowmerz @theonides because you have both x and x^2 you use degree o for both--- prb could use x^2 with A +Bx but that simplifies to Ax and B /x^2

I'm confused. I'm comfortable with equating the numerators and how the denominator was factored. That's fine. Why did my prof recommend splitting the that way? That's what I don't understand. Can anyone advise? The homework is due tomorrow and I'm panicked. 🥴

@mathequalslove sounds like a perfectly valid use of time.

Stuck in a waiting room for the next 3 hours while doing a glucose test. May or may not have got some strange looks when I started cutting some laminated pages. #teach180
