Math Links for Week Ending Nov. 9th, 2017


I was fortunate enough to help organize this year's OAME Leadership conference in locally here in Windsor. We had three keynotes (@ddmeyer, @ctfosnot, @gfletchy) and a bunch of breakout sessions over a day and a half. If you are interested here is the website (which will eventually have links from many of presentations). The theme was Learning in the 21st Century and we had different perspectives on how that can be done for teachers and students. Here is the feed from the hashtag #OAMELead. There were so many quotable lines (even one by me) that I tried to compile some of them  below. Thanks to all those who filled the "back channel" (just a few from @ddmeyer, @markchubb3, @hkodai, @mrbinfeild).

I brought a pile of games to the OAME Leadership conference to play in the evening and other people started to bring up other puzzles. I have to check these and you should too.

There is definitely a math question in here. What question will you ask?

From @ddmeyer's keynote at #OAMELead. The question is: "What is the area of the shaded region?" Do this with a group of students or teachers to see the surprise. The connection could be calculating slope or rates of change on this one but I say that with no explanation :-)

Need a real box plot? What I can't tell is whether this was taken on the inside and the box plot was drawn on the window or just drawn digitally on the image. I hope its the former

Some sketchnotes from @RiversoMaria on the OAME Leadership Keynotes and a couple of the breakouts.

Math Links for Week Ending Nov. 2nd, 2018

Hey, I am helping out with a Twitter chat on Tuesday night at 9pm EST as part of the #esc11math monthly chat. I am going to try to do a combination Twitter chat and live @Desmos activity on some simple geometry problems. So come out and try a bit of dynamic geometry using @Desmos. How do you participate in a Twitter chat, you ask? To be honest, despite being on Twitter for 9 years, I've never participated. My thinking is that the best way is to follow their hashtag and see the conversation streaming. Then if you want to participate, make sure you include the chat hashtag in your Tweet.

And yet another Ontario teacher has published a book. This time it's @matthewoldridge with "Teaching Mathematics through Problem Solving". I like the idea that it looks at problem solving by showing that mathematics can be playful and engaging. Check it out while quantities last.

This week I saw the culmination of an activity I created with @tomsich83 to have students use TI CBRs and Lego EV3 robots to recreate distance time graphs as part of their grade 9 STEM class. Students create an EV3 robot that will carry the CBR and then have to program it to match various distance time graphs. Get the handout at the link below.

If you have ever used the site Open Middle, you know how good these questions are for going deeper on simple knowledge based questions. Here @AliceKeeler has a Google Slides template to use when working with this particular open middle problem dealing with equivalent fractions.

It's always good to find resources on probability that connect to real things that people experience. In this case it's the Monopoly game at McDonalds here in Canada. Specifically, it starts with a piece about some of the fraud associated with the game and ends with a statistician describing the real odds of winning. Thanks to Lorna Baltrusuinas for this one.

In this post @MrOrr_Geek tackles the myth of planning lessons in isolation. I don't think that he is suggesting that teachers don't plan in isolation but instead that some of the best lessons aren't. Collaboration is the key and that collaboration seems to be much easier now than ever before with tools like Twitter, blogs and email. You no longer need to physically be in the same room (or the same city) to collaborate. Check out his evidence (from himself and other Ontario educators) and tips at his post below.

There are a lot of these videos online (and I love every one). None the less here's another plan landing in a crosswind. Perfect for talking about addition of vectors.
