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).

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 :-)

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.

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.

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.

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.

Math Links for Week Ending Oct. 26th, 2018

Earlier this year I posted about @Desmos releasing some Two Truths and a Lie activities, Now they have released four more. These are very simple activities in that they each have one slide with a sample 2T&L and then the second slide is a Challenge Creator activity designed to look like the first slide. A challenge creator is when students are given constraints to create their own problem (in this case 2T&L) and once done, that activity will then automatically be shared with the rest of the class. So in the end your students have a student created activity to practice that particular skill. In this case they have released one for conics, lines, parabolas and exponents. You can see all of their other challenge creator activities here.

Even though on this blog I feature math links related to grade 6-12 math, I don't mind pointing out good stuff that comes out of the Ontario Math community, even when it isn't in that realm. So this week @AliceAspinall published a children's book promoting mathematics. Everyone Can Learn Math is out now and is the story of Amy's struggle to get a math assignment done. Spoiler alert: she finds that struggle and hard work are all part of being successful in anything, including math.

At our board, we have been doing a lot of work on getting kids to talk more and re framing teacher questioning. That's why this Tweet from @MrsSasser offers a nice tweak to how you ask your students if they have any questions.

This is a neat site from @MrBartonMaths called Maths Venns. The idea is that students are given a prompt and some criteria to fill in on a Venn Diagram. There are topics from number sense to functions to data management. You could probably find something for just about any grade level. I could see using this as a prompt on a VNPS. Take a look.

Hey kids Global Math Week is happening starting Wednesday (10/10/18). So many ways you can participate. But at the very least, head on over to www.explodingdots.org and get your kids to sign up to do some exploding dot problems. And if you get this soon enough you can see @JoBoalar's live talk on Joyous Math Facts at 1:25 PM PST on Oct 6th to kick of the Global Math Symposium or just watch the promo video from @JamesTanton to get the gist.

In this latest post from @mathgarden I love that he references one of my favourite courses that I have ever taught. It was a grade 12 course that we had in Ontario called Geometry and Discrete math. I used to call it the "proof" course. It was meant for students going to university and taking things like engineering, physics and math. However, many kids didn't like it because it was hard and it was eventually dropped as a requirement by universities (even though they asked for it to be created). None the less, that is the topic here, that math kids need to experience struggle. The trick is finding the perfect amount for each student.

Not everyone is a Keynote user. Even though I use a Mac, I have never used it either, but the more I see the more intrigued I get. So that being said, if you are at all interested in possibly seeing how Keynote might help you as a math teacher, then check out this iBook from @mathycathy where she explores some of the things you can do for math with Keynote and why making things visual is a good thing.

One of the things I like about the math community on the Internet is we are all into remixing each other's stuff.

I created a simple activity to help students practice plotting points. In it they are presented with a target and have to try to plot the point to get a bullseye. Once they get the bullseye, they can randomly generate another target. It starts with graphing in one quadrant, then goes to four and finally goes to four with decimal valued points.
