Notice how e and pi magically fade away, leaving behind "1/24." The whispers of eternity. tinyurl.com/y5trz4x2
The learning/exploration/experience of most students and teachers of mathematics is a staircase model, filled with cliched gate keeping/checkpoints. The problem is mathematics is more weird and wondrous like an Escher staircase. Be more Escher.
😎 Tomorrow is #WorldTeachersDay! I’m donning my shades from @aitsl to celebrate the #brightfuture that educators help to unlock for their students. Let’s remember the positive impact we have on individuals, families & communities! 🍏

A triangle with three right angles
It is possible to subdivide an equilateral triangle and a square into congruent pieces so that the center of the figure is in the interior of one of the pieces. Can the same be done for a regular hexagon? (For any other regular polygon? For a circle?)
Dan Finkel describes the stages of rich learning from a rich task. 1. Spark curiosity 2. Productive struggle 3. Sense of ownership @MathforLove
Arresting knitting nanas and kettling giant pink octopi. What a time to be a police officer.
This is from page 63 of #MathRecess (just received my hardbound copies) this quote is, for me, the primary reason for writing the book. This week that is #globalmathweek2019 reminds me of these the large goals of learning that should ALWAYS trump test scores @jamestanton
Polar plots of primes. Wait for it... Can you guess what's going on? See the new video: youtu.be/EK32jo7i5LQ

It is possible to arrange 8 dots in a unit square so that each and every pair of dots is at least d units apart with d = 0.5. Find another arrangement of 8 dots with a larger d-value. (How large a d can one get?)
GRAPHING STORIES _15 seconds at a time_ How this works: 1- Pass out the handout to your students; 2- Play any of these videos; 3- Have them graph the story. Link: graphingstories.com This project is a collabotation between @ddmeyer & @Buzzmath Team. P.S. Yes, it’s free!
Teachers running open ended tasks in the classroom need two types of questions in their ‘pockets’: enabling prompts for students who can’t get started and extending prompts for those who finish quickly. Thanks Doug Clarke #manswgreatestshow

In the fall of 1972, President Nixon announced that "the rate of increase of inflation was decreasing". Probably the first time a sitting president used the 3rd derivative to increase the chances of reelection.
A pupil at @WestiminsterUS has come up with a novel way of testing if a number is divisible by 7. What do you think of it? westminsterunder.org.uk/announcements/
This weekend I re-created the well-known 24-GAME-applet. I use this game in my class to practice 'order of operations': make 24 using the operations +, -, *, / and brackets. Free. Should work on all devices. henkreuling.nl/applets/24_gam… #mathematics #mathteacher #teachmath #highschool
