So, I am continuing to be fascinated with the Desmos activity builder, and I am playing around more and more with the card sort feature. (See my initial blog entry on the card sort for an introduction to the feature.) I realized last night that I could do some simple rational number ordering with the card sort and throw in a different way for the students to think about the numbers.
Here's a screenshot of my activity:
The only issue I see is the labels --- this works fine for three numbers (and I have a challenge screen with five numbers), but I don't want the students to get lost with the labels if I had four or seven numbers. As far as I can tell, Desmos does not distinguish between the order of card in a card sort (which would make this a bit easier). But this is a great way to emphasize different ways of viewing rational numbers.
