#ExplodingDots

What are your favorite (potentially long) mathematician quotes? Bonus points if it's not just a pithy restatement of "math is beautiful", but something which changes how you think.

@3blue1brown From @jamestanton explaining how to perform division with #ExplodingDots, and that if you need a dot just draw an antidot... "You can do whatever you want, you just have to deal with the consequences." I've been saying this line at least once a day since I heard it.

#explodingdots @jamestanton @Mathgarden @cbrownLmath @JimPropp @mathemalicious @mathplay3 @magiaymates @lilmathgirl @GlobalMathProj @dhimathorg A #Sunday Special with Exploding Dots. #Math is #Fun and #Visual

#explodingdots @jamestanton @Mathgarden @JimPropp @TijanaMarkovi05 @mathemalicious @GlobalMathProj Derivation of the GP Sum Formula using Exploding Dots... #visual #fun #math

I love this alternative from @joboaler. Rather than a lot of problems, choose 4 and calculate, write a story, and draw 2 visual solutions. #explodingdots

Please spread the word! It's BIG & BEAUTIFUL!! Global Math Week starts 10/10! @jamestanton @drrajshah #explodingdots

#explodingdots @jamestanton @Mathgarden @JimPropp @TijanaMarkovi05 @mathemalicious @GlobalMathProj Weekend Math Fun with Exploding Dots and Cake Puzzle. #math #fun #visual #puzzle

Two steps to problem solving 1. Being your human self and having an emotional reaction 2. Take a deep breath and do something. - @jamestanton #explodingdots

Gotta love the power of place value! #explodingdots @GlobalMathProj @MathPlusAcademy @AIMathCommunity

Showed Y7 this alternative method for subtraction which doesn't require exchanges. Never fails to blow their minds. What are your go-to alternative methods?

As part of a lead-up to Global Math Week 2021 #gmw2021 here's classic Ethiopian Multiplication. It can be explained with #explodingdots. Today's puzzle: Can you make sense of it? (Can you create a base-three version?) @GlobalMathProj @AIMathCommunity @maanow @MathPlusAcademy

Do you like this #explodingdots approach to analysing 0.9999.... ? (It's a place value chart. Ten dots in any one box is equivalent to one dot, one place to the left. Adding a dot and an antidot (that is, a "tod," as kids beautifully call ia) to any box adds nothing.)

#explodingdots @jamestanton @Mathgarden @JimPropp @mathemalicious @TijanaMarkovi05 @lilmathgirl @YamunaN6 @RakhiChawlaEd3D @GlobalMathProj Global Math Week - Time to take inspiration from Gauss and James Tanton ... Enjoy the Exploding Dots Puzzle.

#explodingdots @jamestanton @Mathgarden @JimPropp @TijanaMarkovi05 @mathemalicious @GlobalMathProj The Power of Exploding Dots - Simple Divisibility Rule for 19 ... Enjoy !!

Puzzles that can be explained with #explodingdots. Care to try this variation with your students during Global Math Week ( Oct 10-17? Writeup: The extensions are challenging! @GlobalMathProj @maanow @AIMathCommunity #gmw2022

Here's a stunning new approach to proving trig identities by @GlobalMathProj ambassador @KiranABacche The #explodingdots mindset is astonishingly far reaching! @drrajshah @Mathgarden @mathemalicious @MathTeachCircle @mathigon

#explodingdots @jamestanton @Mathgarden @JimPropp @YamunaN6 @nileshtrivedi @TijanaMarkovi05 @magiaymates @lilmathgirl @mathemalicious @GlobalMathProj @Kweenigma The fun with Exploding Dots continue...

Today's Puzzle Explained with #explodingdots: A calculator, initially displaying 0, has two buttons: - subtracts 1 from the number on display; x multiplies it by -2. What is the least number of button presses needed to make 100 appear on screen? How know least? @GlobalMathProj

The life of an international math star - waiting for an Uber at the Sheraton San Gabriel someone (a lovely middle school principal) runs up to @jamestanton shouting #explodingdots!! For a selfie. Never met before!

Try this classic Five-Card-Mind-Reading Trick with some friends. And explore some extensions and variations too. @GlobalMathProj #explodingdots

Given a number, erase its final digit & subtract double that digit from what remains. Original number is a multiple of 3, 7, 21 only if the new number is. Why? Keep going. Get divis rules for 3, 7, 21! It's Global Math Week #gmw2023 for #explodingdots fun.
