Gave this warmup question to my class today. Students had to think carefully about the function and what x represents in each statement. Great discussions. @studymaths.bsky.social #ITeachMath #MathSky

#TryThisThursday

Try Would You Rather as such a great routine to get students thinking and sharing about mathematical relationships.
Which is your favorite and why?

I saw this come across one of my feeds and I thought it was fake. But it turns out that in 1979, the #Casio "Calculighter" was legit

Demonstration of Triangle Sum #iteachmath #geometry

A photo of a piece of paper with a diagram being drawn. A grey horizontal line is labelled "number line" and has points marked 0,1, a and b. A red line goes across the top left of the page and is labelled "away". A blue line goes acrosds the top right of the page and is labelled "home". A red line parallel to the away line goes up from 1, and meets a blue line parallel to the home line that goes down to a. A green line goes from 0 through the point where red turned to blue and continues upwards. It's labelled "turn line". One hand holds a ruler in place through the point marked b parallel to the "away" line, while the other hand holds a red marker and draws a line along the ruler to finish on the green line marked "turn line".

New blog post about my method of doing addition and multiplication using the geometry of parallel lines. It's called "Home & Away: Gometric Arithmetic". davidkbutler.xyz/2026/04/10/h...

Using Student-Created Stop-Motion Movies to Explore Math Making simple movies provides early elementary students with chances for rich mathematical discussions.

Stop-motion movies are made by recording one small change at a time—the perfect medium for capturing several fundamental math concepts! 📹

Twenty four clusters of tiles that look like 3D clusters of cubes, each with a differing number of cubes.

#ElemMathChat Q7 “Last Tile Standing” is another one of my favorites (for Tile Farm’s version go to tiletalk.tilefarm.com). I’ve chosen one of the 24 patterns above, can you think of yes/no questions that could help eliminate options? Ask and I’ll answer yes/no. Can comment below if easier.

The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six identical double hexagons around a central teal hexagon. Each double hexagon is composed of two heptagons joined together using darts. The gaps between the double hexagons are filled in with regular hexagons made from six teal kites. The first image along the bottom shows the double hexagon made from two gray darts, four teal kites, eight green triangles, and ten blue rhombuses. The rest of the images along the bottom and on the right show the progression of the design.

Pattern block play! #21CenturyPB #iTeachMath

Mathematicians can’t agree on whether 0.999... equals 1 Whether 0.999... equals 1 is the subject of bitter dispute in countless online forums

Oh no! #MathSky friends! According to a theoretical physicist and Scientific American, we just can't agree! Even if it doesn't lead to any more contradictions that calculus.

Thinking Thursday: Leo Tolstoy Writing to Learn Math: What did the author mean? Put the thought in your own words. Do you agree or disagree? Why? Do you want your children to develop the ability to reason creatively and figure out things on their own? Help kids practice slowing down and taking the time to fully comprehend a math topic or problem-solving situation with these classic tools of learning: …

Percentage of Canadian Population that is Asleep, by Time of Day Percentage of Canadian Population that is Asleep, by Time of Day

New #SlowRevealGraph:

How many Canadians are awake at any given time of day?

A 4×4 puzzle grid featuring summer symbols. Each symbol — umbrella, sandals, glasses, or sun — represents a prime number. Each row has a total shown on the right, and each column has a total shown beneath it. Rows (top to bottom, left to right): Row 1: Umbrella, Sandals, Glasses, Sandals. Row total: 282. Row 2: Umbrella, Sandals, Sun, Glasses. Row total: 290. Row 3: Sun, Sandals, Sun, Sun. Row total: 308. Row 4: Glasses, Umbrella, Glasses, Sun. Row total: 292 Columns (top to bottom using the first image in each row): Column 1: Row 1 Umbrella → Row 2 Umbrella → Row 3 Sun → Row 4 Glasses. Column total: 286. Column 2: Row 1 Sandals → Row 2 Sandals → Row 3 Sandals → Row 4 Umbrella. Column total: 280. Column 3: Row 1 Glasses → Row 2 Sun → Row 3 Sun → Row 4 Glasses. Column total: 304 Column 4: Row 1 Sandals → Row 2 Glasses → Row 3 Sun → Row 4 Sun. Column total: 302.

Continuing with the prime theme, here is today's summer inspired #OCRMathsPuzzle.

Each summer symbol in the grid below represents a prime number.
The sum of each row and the sum of each column are given.
Work out the value of each summer symbol.
