Global Math Week cometh: Oct 10-17! Five piles each 100 coins. Each coin ideally 100g. But maker could have cheated & made each coin in some piles 99g or each in a pile 98g. Select some coins & get their total weight one time. You can find the cheat piles! globalmathproject.org/

One month from today is the start of Global Math Week 2022! Be on the lookout for what we @GlobalMathProj has in store for you! Share your joyous math with the hashtag #gmw2022 or, if you are doing them dots, with #explodingdots! @AIMathCommunity @maanow @MathPlusAcademy

It's not too late to enter the @GlobalMathProj MATH IS __ video contest! globalmathproject.org/events… Ask your students what MATH IS to them. So, compelling! @AIMathCommunity @MathCircleNet @MathPlusAcademy @maanow

Lot's afoot with @GlobalMathProj! Logic Gates & Dots, and videos in Sinhala, and the MATH IS __ video competition still underway.

A recent talk on the @GlobalMathProj: What it is & how it came about. Talk now public. youtu.be/q51_X8U9JkQ I was v. nervous giving this. I even used the word verklempt out of nerves. (Who says "verklempt"?) But it's true, I was actually verklempt. @AIMathCommunity #iteachmath

Here's a picture of 4x5. It can also be viewed as a picture of 4x3 + 4x2. So, it must be that 4x(3+2) and 4x3 + 4x2 are equal. This idea leads us to say that, in general, that axb + axc = a(b+c) for any three counting numbers a,b,c.

So lovely to have #explodingdots videos in Sinhala added to the @GlobalMathProj resources. Thank you Dr. Jayakody! globalmathproject.org/ @AIMathCommunity @MathCircleNet @MathPlusAcademy @maanow

Vids are coming in for the @GlobalMathProj MATH IS__ contest. One teacher wrote "My emotions were out of control when making this video! There was lots of crying, laughing, and of course, unexpected answers." Details: globalmathproject.org/events… @AIMathCommunity @MathPlusAcademy

G'Day Star Trek Team @gates_mcfadden @jonathansfrakes @TheKateMulgrew. For some reason all your lovely tweets are being forwarded to @GlobalMathProj notification.Not sure why. Are folk in your community interested in grassrts math outreach?(A v. basic vid youtu.be/Pmqw2e7A64Y)

Base i+1 anyone? A lovely piece from the inimitable @JimPropp that explores a stunning question posed by his fabulous daughter. mathenchant.wordpress.com/20… @GlobalMathProj #gmw2021 @maanow @AIMathCommunity @cyfemat @MathPlusAcademy @MoMath1
