How To Teach Area of a Circle Through Problem Based Lessons

Sneak-a-Peek Into an Online PD Webinar Experience

Both Jon and I have been really enjoying spending time creating videos that unpack effective mathematics pedagogy and help to build the mathematical content knowledge of educators!

Not long ago, we gave you a sneak peek into a grade 7 virtual classroom where we emerged Pi (π) through an amazing problem based math lesson called Tile Circle. This time, we’re going to leverage the same context, except we’ll be asking students:

How many tiles will it take to fill the circle?

While students might not realize it immediately, we’ll be uncovering the big idea of area of a circle and emerge the formula by asking them to make estimates and to use their prior knowledge without just gifting them the formula, A = πr^2

While we’ll be modelling how to teach the area of a circle through this fantastic curious lesson, note that the full Make Math Moments problem based unit has not been published as of this date, but it is coming soon!

As we do in each problem based math lesson we lead, rather than simply pre-teaching concepts, we’ll be using the Curiosity Path to dive into a context-rich problem.

Watch as we dive into an edited ‘summary’ of this online teacher professional development webinar where we share some of the key parts of the lesson and strategic purposeful questions we can ask students to guide through a productive struggle.

Give a quick watch below and note that all relevant links are located below the video.
