    First of all, we used the hot chocolate take in my Math 8 class, and although the students all lamented that “nothing happened” because it was just someone putting out a glass and can of cocoa, they were all watching and then I had so much buy in as we discussed different quantities of scoops and glasses. It was much more interest than if we had just started by comparing numbers in a table.

    Anyway, I agree that it what we use depends on the situation. For me, if we can use a unit rate or friendly number, I am more inclined to use a rate, such as 3 scoops per glass or 25 mpg.

    Today in class we compared sides of similar triangles, so we had a 3:2 ratio, for example, of all the sides and that seems like a situation where a ratio seems more comfortable than a rate.
