This morning I generated three new Activeprompts related to area and understanding the relationship between dimensions and the area of an object. I’m hoping to use these as examples of questions teachers can use to prompt good questions from their students and generate discussion around mathematics.
I sent out the prompts via Twitter, and one person responded with a great question.
@davidwees Define biggest? The area of each from left to right measured (on my screen) 14.95, 14.44, 13.44

Of course, this is exactly the kind of question I’m hoping students come up with.
