A speedy drag-and-drop task for anyone tempted to “solve” an identity. It often reveals other misconceptions too.

✏️ NEW BLOG POST ✏️

I need to be less concerned with being better at writing and more concerned with hitting PUBLISH.

I *think* this is about teaching math.

Curious what my math friends think of the use of AND on this sign...
Wondering if dogs OR alcohol are allowed on the beach, just not at the same time?

📊 #dataviz #history Who invented the bar chart? Everyone credits William Playfair in his 1785 Commercial and Political Atlas

I give that honor to the cartographer Phillipe Buache for lovely 1767 chart of the heights of water along the Seine.

But there's more ⬇️
A proto bar chart by Buache 1767. Titled: Echelle du Pont de la Touradelle. The columns show the height of water in the months Jan. - Dec, probably averaged over several years. Horizontal lines show some events, like a flood in 1740. A similar chart from 1770 for the Seine, with a numerical table at the top. Portrait of Phillipe Buache

Statistics Supplied is a great exercise for deepening students' understanding of mean, median, mode and range. It's the reverse of the traditional exercise.

Have a go at the first few questions yourself!

I didn’t get dumber every day, but for the past four years I was never challenged (or expected) to go beyond teaching to a test. Trust me, I tried. “Pump the brakes” and “stay in your lane” were the expectations. I’m glad to have found a place where that is definitely not the case. #EDUsky #mathChat

Abstract
Polytopes are one of the most primitive concepts underlying geometry. They are defined as intersections of a finite number of half-spaces...Advances in A.I. provide mathematicians with yet another powerful tool in advancing mathematical knowledge.
