Disproportionately Awesome

Right now in Algebra we're working on proportional reasoning and the various strategies one can use to solve a proportional reasoning problem. On Friday and Monday, groups wrote their own proportional reasoning problem and then displayed the different ways they could solve it. Here are the highlights:

This group was having trouble coming up with a problem, so I asked them what kinds of things they're interested in. One kid said "shopping." That's easy--there are lots of things you can do with proportions and shopping. "Okay, so what about shopping?" I asked. "Like how much something might cost?" They chose another approach.

In this group, they didn't have much trouble coming up with their problem, but they started out with a given that Yesenia has three boyfriends in one month. I encouraged them to pick more difficult numbers than one. They said three months, so I asked, "So how many boyfriends would she have in three months? Five maybe?" "Oh, no!" one girl responded. "That's definitely not enough boyfriends in three months." My favorite part of this poster is that the points on the graph aren't just points, but hearts. "Because it's about my boyfriends."
