Use this Loop Puzzle to review Proportionality with your students. Loop Puzzles are much like the traditional "I have, Who Has", but students must each work every question. I hang each question in the hallway and students work through the Loop during class. They start with a question (at the bottom), then work to find a solution. Once they have done that, they look around the hallway to find their answer (at the top). They walk to that paper, then work the next question (the one underneath it their answer.) If they answer all of the questions correctly, they should loop back to where they started. This is a GREAT resource to use as a formative assessment that is also self-checking. If they don't see their answer, they know they've done something wrong.
This specific loop puzzle includes 12 questions over:
-Percent of a Number
-Constant of Proportionality
