## Area of Saskatchewan

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...

## Giant Rubber Duck

More #Canada150Math Challenge 3 Act Fun! We are cruising through week 2 of the #Canada150Math Challenge and I was inspired by @NatashaMFolino to create the visuals for this task when she shared the following tweet on the #Canada150Math hashtag: https://twitter.com/NatashaMFolino/status/870701672011517952 For those who aren't aware, the Giant Rubber Duck will be making a visit to Toronto and five other towns in Ontario for Canada's 150th Birthday during the summer. There are some articles here, here and here that might inspire other questions for you to use in your classroom. We will be continuing the challenge all month long, so be sure to check them all out here. See All Questions Act 1: Introduce the Task #Canada1...

## The Great Canadian Flag

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

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 ...

## Solar Panels

Proportional Reasoning With Green Energy This is a 3 Act Math Task that focuses on "Green Energy" proportional reasoning questions related to solar panels in order to address proportions both visually using area models and proportions written as equivalent fractions. Special thanks goes to Dave Raney from CPE Inc. for allowing us to use his video and photos as well as Kathleen Quenneville, Energy & Environmental Officer at GECDSB for her feedback to create problems around solar energy. Act 1: Introduce the Task Show students the act 1 video. https://youtu.be/TVNelm5Xgtk Then ask students to do a rapid write of what they notice and what they wonder. Students will then share out their noticings and wonderings while ...

## Problem Solving With Super Bear – A Spiralled/Interleaved Approach

Spiralling Through the Curriculum With (too much?) Structure Yesterday, I shared a task template I created for Dan Meyer's Super Bear 3 Act Math Task colleagues from the Math Twitter Blogosphere (#MTBoS): Super Bear 3 Act Math Task Template is now up. Feedback? —> http://t.co/QAboGiKKDn #MTBoS @ddmeyer @mathycathy @mr_stadel @robertkaplinsky— Kyle Pearce (@MathletePearce) March 6, 2015 Some of my best learning and growth happens when I toss my ideas out there and ask for feedback from a wealth of math instructional knowledge from around the globe. Some feedback was positive: @MathletePearce Love template structure & emphasis on multiple representations to help Ss extend task! @ddmeyer @mr_stadel @robertkapli...
