Recently, I teamed up with Math For Love to bring an idea for a scaled set of pattern blocks to life. The result was the creation of Upscale Pattern Blocks.
(You can read the origin story of this new set of pattern blocks here).
Dan Finkel (the founder of Math for Love) has created some Fraction Talk images that take advantage of the new, scaled pattern blocks and posted them in a free lesson on his website.
The images are also available on this site under the “Manipulatives” photo gallery.
This year, I was honoured to be asked by Christina Tondevold to submit a webinar to the Build Math Minds Virtual Summit 2019.
In it, I describe the history and emerging community behind the Fraction Talk idea, website, and activities. You can find the full webinar (along with some support materials) in this Google folder. Continue reading
One of the earliest Fraction Talk ideas to come from the community of teachers that took up the idea was that of Fraction Talk War. As described in this earlier post, teachers began to use Fraction Talk squares in familiar game structures such as war to elicit student decision making. I have received numerous website replies and social media notifications from teachers who have used this idea with their learners. Initiatives like these are what makes online teaching communities so powerful: Somebody has an idea and we all can run with it in ways that fit our learners’ needs.
Enter Carla Dawson.
This last week Graham Fletcher (among others) alerted me to a twitter thread posted by Jo Morgan. In it, Jo posted a series of activities from an old textbook she had come upon (The book seems to be part of a large series from the late 1920s & early 1930s: Fundamental Arithmetic, by P. B. Ballard.)
