Is the 6" or 7" slice of pizza the better deal?

This is great from @howiehua.bsky.social I have always called these "equation strips" but definitely love them for solving 1 and 2 step equations. Here are some resources I've put together

A deep blue mottled annulus surrounds a black hole, or the moon's disk during a total solar eclipse. On closer gaze, silver ant-like shapes follow each other endlessly around a torus. The torus is tiled with a golden hexagonal grid. Each ant is isolated in its own cell.

The Power of Slow Reveal Graphs Teachers can leverage students’ curiosity to explore visual representations of data in an engaging way.

By revealing graphs piece by piece, teachers can build student curiosity and guide them to more effectively make sense of data! 📊

The image shows a twelve-sided shape created with 21st Century Pattern Blocks. It was built by arranging 6 rectangles and 6 equilateral triangles around a central regular hexagon with each side of the hexagon measuring 2*sqrt(3) inches. The design uses teal kites and pink triangles.

just a fun #MathsToday counting problem my colleague set out, which was solved in an unexpected way by students:

How many ways can you arrange the letters A through F such that (A comes before B) and (C comes before D)?

teacher expected: 6!/4=180 (all arrangements, ½ for each condition). Instead:

It’s about the benefits of teachers tinkering with the problems/prompts we offer students.
