Ratios Fold it Up!

Getting started with ratios!
We pretested ratios, rates, and proportions last week, and I found mixed results in the item analysis. I was surprised to find that very few students were able to write a ratio (the pretest question was: there are 2 hamsters and 1 gerbil - write a ratio of gerbils to hamsters). It wasn't that they wrote the ratio as hamsters to gerbils rather than gerbils to hamsters....they either left it blank, or wrote something that did not resemble a ratio. So, I was glad that I had prepared a couple of Fold it Ups for them to use this week!

I think this is the first time I've used this version of Fold it Up (with the triangles folded in) this year, and a few students commented that they like this version better than others (like the one I made for Wed...bummer), because this type won't rip as easily.
