Did the Dog vs People Names scatter plot today with a room full of k-12 computer science teachers, and WOW, the discussion we had! 🤓 #slowrevealgraphs

New lesson added to our free lesson library!

This is an expanded writeup of my original @nytimes.com Numberplay writeup from 2015. Features a tie-in to my more recent @ted-ed.bsky.social riddle too!

Great for grades 4 - 10.

Dot Paper Task A low-tech task with high-level thinking

One of those heart-FULL teaching days:

My Attempts at Estimation 180 tasks - YouTube Andrew estimates tasks that he has not seen in years.

I'm having a blast revisiting Estimation 180 tasks.
My next attempt: Cheeseballs day 207. www.youtube.com/playlist?lis...

If you missed 206...it's there too. #estimation180 #iteachmath #mtbos

This year, I joined NCSS (social studies) as part of my registration for their national conference. (I presented about slow reveal graphs!) Today, their journal arrived.

What a beautiful surprise to see an article from fellow math educator/SS enthusiast @mathillustrated.bsky.social! 🤩

With CBC now having called all ridings it's time for the land-vs-people-vote animation.

Can you solve the puzzle? What goes in each blank of the area model? A 2 row by 3 column array is shown. To the left of the array, a 2x is shown in row 1 and a 3 is shown in row 2. A 10x^3 is shown in the 1st row, 1st column cell. The rest of the cells and the 3 spaces above the first row all have question marks. Under the array, the total area is given as 10x^3 + 23x^2 – 4x – 24.

Launch for tomorrow's polynomial division lesson. #iteachmath #MTBoS

Join me for "Multiplication: More Than Repeated Addition and Times Tables" at the 2025 @mypita.bsky.social Spring Conference in Squamish on May 9!

Q6: How many stickers could there be in the bag? #ElemMathChat

Q1: I drew some polygons on dot paper. I labeled each with 3 numbers. What do you notice and wonder? #ElemMathChat

If 100% is 400, what other percentages can you work out? The picture shows a bar split into 10 large sections, each marked into 10 smaller sections. Markers above the bar show various percentages, while markers below it show the corresponding amount for each percentage.

Four problems about the height of two stacks of congruent rectangles.

Four problems about diagrams made up of congruent rectangles drawn on a coordinate grid.

Three problems that can be represented by simultaneous equations: one about the length of two strings of square and circular beads, one about the weight of a bucket containing different amounts of water, and one about the value of a given number of coins.

Applications of simultaneous equations might be my favourite topic. There are just so many fun problem types! We did these Don Steward beauties in Y10 #MathsToday.

This is the coolest, strangest thing you will watch (and likely re-watch over and over) today

The Real Environmental Impact of AI | Earth.Org In this article, we delve into the environmental impact of AI, exploring associated problems including emissions and e-waste.

And I must protest the statement in the "Integrating AI into the Arts" lesson that "Digital tools are 'green,' making them environmentally friendly from a climate justice and sustainability perspective". They may be inclusive but they are not environmentally friendly. earth.org/the-green-di...

I love reading the small details about how Marilyn launched and facilitated the task!

Three square pans full of unbaked dark fruitcake, one large,one medium, and one small are sitting on a brown kitchen chair.

Made fruitcake from an old recipe that makes one large (8x8), one medium (6x6) and one small (4x4) cake.

How would you turn this into a math problem?

The picture shows the word power with subscript 2 of 8 equals 3 and power with subscript 5 of 25 equals 2, followed by nine more without the value for students to figure out.

#MathsToday
Today was day 1 of logarithms in #MHF4U so I presented students with this, inspired by James Tanton.

This is a nice problem for students to think about!
