Math Links for Week Ending Mar 27th, 2020

Featured Links
So I think many people have been asking for this feature on @Desmos activities for a while and I don't think it could have better timing. Being able to give direct feedback to students right in the activity is the perfect thing needed right now as we are out from our schools. Keep in mind, ideally, it would always be better to be able to talk to students directly while doing an activity with your students but given the situation we are in, this is a nice addition.

Resource Links
If you like Skyscraper puzzles then check out these two resources. Firstly @MarkChubb3 has created some new ones that you can download from his site. And as well, this Brain Basher's site has randomly generated ones that you can download as well. Now of course, you could do these by just placing the numbers 1-4 in each row and column so there are no repeats in either but it's way more fun to actually "build" the skyscrapers with snapcubes or legos.

I have been finishing up and creating some new @Desmos activities to help with the distance learning dilemma. A lot of the new ones I have been creating are self checking so that students know how they did right away. These two are for adding and subtracting fractions and they both are organized in a progression of simple to more complex questions with visual and numerical representations. And both end with a Challenge Creator for students to create their own questions for the rest of the class to do.

I also created a quick activity that deals with composite areas created with rectangles. Students see areas in the contexts of parking lots, roofs, parks and farms and then have a Challenge Creator where they can create their own composite area for the rest of the class to solve.

Finally I created a beginning fractions activity that is rooted in pattern blocks. Students have to start by saying how much of each shape is made of each shape or colour. Answers start as whole numbers and then move to fractions. Then the questions become more challenging. All of the slides are self checking.

Everyone is talking about assessment now. That is, how do I assess in a distance learning model? Though this post is from a month ago (before our current situation), I love the suggestion of allowing for students to choose the difficulty of questions they do on an assessment.

And seeing as I have been making a lot of self checking activities. And so with that in mind I have made a collection of all of the activities that have that self checking feature. But on top of that I have created a two slide template so that if you wanted to create your own self checking activity you could. And to help out, I created a video on how you could do that. Now I know that many of these activities only ask surface and basic questions but sometimes we need our kids to practice and these are ways they can do this while still knowing if they are doing it correct. You can get all of my self checking activities, including the template here.

In the area of Covid-19 based videos, this one from @numberphile is a deep dive into both the calculus of exponential growth and a real time Geogebra tutorial.

And you may have seen a lot of sites with mathematical models of the spread of Covid-19. Many of those are based on some sort of exponential relationship (like the one above) but @3Blue1Brown has done his simulations all based around probabilities and made them all delightfully visual.

I mentioned this mathematical mistake a couple of weeks ago but I like how @StandupMaths reiterates the idea that when put on the spot, it's quite easy to make math mistakes. But he also goes through some more specifics about why people make this particular mistake

I love this image from @MonaChalabi. Have your students take a look and ask what they notice and wonder. So interesting to connect what countries are doing/have done and how their Covid-19 data looks

And of course it's always good to have a bit of mathematical surprise
