Yes, I have done lots of stuff with interacts. But yeah, I also am trying to coax the kids to realize that they can think with this. A lot of these kids are not strong mathematicians, nor do they have much of a background in programming. They are extremely easily intimidated by symbols, so the fewer the better. I start by having them do really simple things like use interval notation to create sequences and then move on to list comprehension. I'm making list comprehension a core standard. Many students find it challenging, but getting them to persist in understanding it really pays off. You can model so much with it, from plotting ordered pairs to articulating sigma expressions. Since it's based on set builder notation, it has a whole lot to do with the mathematics we want them to understand in the first place.
But the fact that you can then add interacts to core code you've created is fantastic. It's actually timely that you mention it right now, because it could be a great thing to do tomorrow : ) On Thu, Nov 20, 2014 at 7:52 PM, kcrisman <[email protected]> wrote: > Awesome! > > Have you done much with interacts?
