Math Links for Week Ending May 1st, 2020

Featured Links
Although I don't often repeat posts, because I am helping with the organization here, I am taking some licences and reminding people that our virtual math conference is happening starting Wednesday and there are over 3000 people already signed up. OAME 2020 Virtual features 30 live sessions and over 20 pre recorded sessions on May 6-9th. When you register you will be registering for the conference but not picking sessions. We will just be sending you links each day for the day's sessions. The conference is free to all but the recordings (both live and pre recorded) will only be open to the public until the following Monday. Check out the full program and get registration details at the link below

I know I have been posting a lot of @Desmos stuff lately but I know that people are looking for things they can use online and I think that the ability to comment and watch what kids are doing in realtime then it's a great tool. That being said, here is an activity that I created to help kids develop an understanding of fraction division without directly telling them. And as a bonus, it's self checking and there is a Challenge Creator so students can create their own devision problem for the rest of the class to try out.

Some great tips from @JReulbach on things you can do at home to hack together a studio for making videos. And I highly recommend the same stylus she's suggesting. I use the same one.

Opinion Links 
I am a fan of good information and in this post, @RobertKaplinski is telling us about some of his favourite non fiction books that are not about education that every teacher should read. And I have read four of five but my fav from the list is Made to Stick. I wouldn't miss it.

Video Links
I totally love this video from @StandupMaths and @FryRSquared about the dangers of false positives. This was recorded last December but it's totally topical now where there is talk of the accuracy of Covid tests.
