Area of Saskatchewan 3 Act Math - What Do You Notice? Wonder?

Introducing the Area of a Trapezoid and/or Composite Figures in 3 Acts Here we are in week 3 of the #Canada150Math Challenge and after finally moving west to North Vancouver to mathematize the Canada 150 Mountie salute on the Capilano Suspension Bridge, I thought we should head to the prairies to see what sort of math fun we could have there. This question was inspired by an old EQAO problem from the Winter 2007 Applied Assessment of Mathematics about the area of Saskatchewan: Doesn't quite generate that mathematical excitement I am typically looking for, but still a worthwhile problem. I'm thinking we could have a lot of fun with this and maybe even spark some curiosity at the same time. Act 1: Introduce the Task #C...

Canada 150 Math Challenge - What Do You Notice and Wonder

Starting a Month of Math to Celebrate Canada's 150th Birthday As you might have heard, 2017 marks Canada's 150th year of Confederation and me and my Canadian friends are pretty excited about it. You can probably imagine how geeked I was when Heidi Horn-Olivito came to me with a math challenge that she and the collaborative inquiry team at Dr. David Suzuki Public School thought up around Canada's 150th Birthday. They originally wanted to challenge our district, Greater Essex County District School Board (GECDSB) to a month of Canada 150 Math during June. However, I've upped the ante and I'm challenging all of Canada. While we'll be providing a math question and/or provocation during the entire month of June via the @Canada150Math T...

Sticky Note Challenge


Sticky Note Challenge 3 Act Math Task Featured Image

Ratio, Rates and Proportional Reasoning With Sticky Notes This is a 3 Act Math Task that focuses on ratio, rate and proportional reasoning related to a video shared with me recently on Twitter from Jerrold Wiebe‏: https://twitter.com/Jerroldwiebe/status/865176406136942592 In the video by Design Squad Global, a man sets up a Sticky Note Challenge involving the "shear" of the sticky notes to determine how many sticky note "slings" it would take for him to lift his own weight. I immediately thought that could be a fun situation to mathematize in the classroom. Act 1: Introduce the Task Show students the act 1 video. https://youtu.be/nVyhDO5lxaQ Then ask students to do a rapid write of what they notice and ...
