Question for #MTBoS #iteachmath: What are your favorite websites to go to for either (1) Warm Up activities or (2) 3-act math tasks? Some of the sites I've used over the years have moved or are no longer active. So trying to get some fresh ideas and update my list!

♾️ Spending my day talking with @mrkitmath.bsky.social about the complications of subtraction and division compared to addition and multiplication. We know division can be classified as partitive or quotative. Does subtraction have similarly clear words to denote distance vs removal?

The #OAME webinar w/ @mathematize4all.bsky.social was 👌🏽. While many want simple answers for serving disabled students in math, Rachel reminds us that disability is complicated. But, listening to students will help us design more open math classes that work to include everyone #iTeachMath #EduSky

A picture of a slide with a quote from Rachel Lambert’s book, “Rethinking Disabilities and Mathematics.”

The quote is: “When we as teachers trust in the thinking of our students, especially our students with disabilities, we create the conditions our students need to trust themselves as mathematical thinkers. When we, their teachers, believe that our students can and will solve complex problems, they will be able to.”

#MathsToday (from Thursday) Introduced Sum of Squares (sometimes known as Pythagorean theorem) with this activity. I showed a list of triangle side lengths which they drew on 1 cm grid paper and determined whether each made a right angles triangle. As a class we determined 👍 or 👎.

Upper left: a circle.
Upper right: a many-sided regular polygon.
Lower left: an ellipse at a jaunty angle.
