I've uploaded the PowerPoint we talked through in class. It's in two parts, firstly because it was too large! But, it's worked out quite nicely because information is presented in the first one and then discussion points in the second.
I've also linked to a few videos about rationing for you to watch as well, but I'm sure you can find some of your own. If you think you've found a good one, then please send me the link on Dojo!
I will leave this task open ended for you. If you would like to create something to show the information you have learnt, you can do that in any way you like.
