Math Links for Week Ending Aug. 24th, 2018

Worksheets have been a big part of math classrooms for years. But more and more we are seeing the value of not using a worksheet (or at the very least, modifying the structure of that worksheet). In this post @AliceKeeler gives some tips on how to make a worksheet into something electronic (even for math). The thing that resonated with me was this quote: "f kids can Google the answers, the worksheet is OBSOLETE!"

A lot of people are back in school (in the US) but here in Ontario we don't start until the first week in September. And if you are looking for some ways to start the year off then @SaraVDWerf has you covered with a post with a bunch of ideas. This post is actually from last year but it is still gives ideas on things like what it's like to be a mathematician, classroom norms and classroom set up (even if you just go to get a glimpse of her Calculator Museum it's worth it). In fact, I put the tour of her classroom in the video links below. And don't miss her 180 days of math puns/jokes/thoughts.

If you were at #TMC18 this year (or at least on Twitter around that time) then you probably saw @MFAnnie's Notice and Wonder sticker set. Now you can own your own by purchasing them on Ebay. It looks like they are selling fast so get them while their hot.

The title of this post from @rickwormeli2 grabbed me right away "It’s Time to Stop Averaging Grades". I have long said that using percents and averages gives a false sense of accuracy. Read on if you are intrigued. Thanks to @scnmathdude for pointing this one out.

I think this sort of short video giving the "Reader's Digest" version of how to run a Desmos Activity Builder is perfect to show teachers some of the ways you can facilitate using these activities in their classes. It's really short but it's packed full of insight. Hopefully there will be more of this.

I'm not sure what good this would be in a math class (though check out the Desmos constructions of it in the comments), it is called a do-nothing-machine. But it sure is fun.
