@Mathgarden @realJ_Mitchell Math should be a pump, not the filter! It should inspire the brilliance inside the minds of young people, not prevent them from flourishing.

@kathyhen_ And the City is not in Cali either.

@DavidKButlerUoA Yes it is “index” in the US at least. I would not be surprised to hear called the “radix” either.

Is there a name for the little number inside the tick of the radical when you do cube roots, fourth roots etc? Is it called the "degree" or the "order" maybe?

@RochieWBZ @dunkindonuts So far you’re right. The rest have sucked though so not much competition.

And the winner of best #SuperBowl commercial is… (@dunkindonuts) twitter.com/dunkindonuts/s…

Wanna understand what happened in Iowa & why Evangelicals voted even stronger than they did in 2016? And why it’s quite possible we’ll have Trump for a second term? It’s all in Jung. This from The Undiscovered Self, 1957. BTW, this applies equally well on both sides of the aisle.

@jamestanton Is/Are there a generalization(s) to be made if that trace point is on the circle?

A circle of radius 1 rolls around a convex polygon. Its center traces out a new shape. What is the perimeter and area of the new shape compared with the original shape?

@Educ8Liber8 @alicekeeler Please do tell me that your K teachers need to also know stuff, have studied how 5yos learn, what the role of play is in learning, etc. please don’t make the only criteria some nebulous “pure and gentle heart” mumbo-jumbo

@alicekeeler Love it! Similar goals at the microschool I am launching in Sarasota, FL!

Look at this teaching job. They are advertising work life balance!! Looks like some places are starting to get it!!

@pwharris Ooo again I see eleven squared for 121 (hold that for a moment) now I see four times five yeah that’s 20 Two 121’s is 242 by 2 is 484 by ten is 4840

@alicekeeler He really should plan a half dozen or so super engaging and interesting lessons of his own, then teach them. Bring in stories from working in the real world. And most importantly, get ready to be lied to, ignored, and told to “f@ckoff” by people ¼ his age without flinching

My dad is retired (engineer) and is thinking about substitute teaching in Texas. What advice would you give him for how to be successful at being a substitute teacher?

@pwharris Let’s see, there’s 6x121 =726 But you need three of those so 3x726 dang that requires writing stuff down ummm 2100 and umm 60 plus 18 So…2178

@DrP_Principal A means by which children’s brain cells were depleted by the incessant smelling of paper?

Anyone know what this is?

@alicekeeler Is it a pencil case?

Look what I just got!!!

@alicekeeler @TheCoachRich Wait, what!? I should closely examine the results of my AI assistant? Maybe this is something we could teach kids about when using any LLM? /s

@TheCoachRich Thank you!!! I used Google Bard to help me create the data... I updated a few of them that seemed off.

Dear #Mathchat folk, Discuss so a 3rd grader can understand if it is always the case that adding six copies of any number will always result in a number evenly divisible by six. If you disagree, provide a counter example. As always, play nicely.

@RyanMath6284 @alicekeeler Yes it is. We need better answers to the “Why is this important?” type questions

@alicekeeler @cbrownLmath Mathematics education is in desperate need of an overhaul

"Why should factoring have any prominence in assessing college readiness?" @cbrownLmath

@RyanMath6284 @alicekeeler No, what is the purpose of crowding the curriculum with tasks like this? In all my 35 years of math teaching and research, I have never seen an argument that persuades me to maintain the practice.

@alicekeeler @cbrownLmath Is this a rhetorical question?

@DavidBegnaud Nahhh you’re not middle aged because of getting the membership. Now if you start going there just to eat the free samples as a light lunch alternative… Chances are you’re either middle aged or parenting teens who will turn that light lunch into a competition.

I joined Costco today to buy one item. Just. One. Item. I didn’t even make it past the first display on the other side of the welcome door. Toothpaste. The kind I like. $25 for five packs. I left with $500 worth of items. They sell gas. The line was so long it looked like what I see when I’m covering a hurricane and the storm is about to make landfall and people are scrambling to get the last bit of fuel. Is Costco giving it away for free? 😳 The shopping cart was so big I could’ve slept in it. I pulled into the parking lot and thought there was a concert I wasn’t aware of. I needed to get in and out. I was in there for an hour and 20 minutes. This is not normal behavior. 🤣

@VictoriaTheTech Congratulations! I have a black tie you can borrow though. Save the time and money shopping.

Kourt and I have a black tie event to attend this month (one where I will be honored for my achievements!) so we’re currently shopping for our gowns.

@pwharris Call it 700. Until a level of precision is needed who’s to say I am wrong?

@dhabecker Ooo what a catchy idea!

@cbrownLmath It’s almost as if this playful mathematics you are envisioning is some sort of math recess.

Do you know what makes students think math is fun? When they understand it. We don’t have to make math fun…it already is. We just need to find better ways to help students learn it.
