This is an activity that includes basic matrix operations (addition, subtraction, scalar multiplication, and multiplication). ANSWER KEY IS ALSO INCLUDED. Students have their paper where they record their answers, but instead of a traditional activity where they simply write their answers, answer sheets are included that can be hung around the room. This allows students to have immediate feedback on whether or not their answer is correct, because if it isn't on a paper that is hanging around the room it must be wrong! Answer sheets are lettered A-H for quick reference. HOWEVER - there is a mix thrown in! In the past, once students get the correct answer to half the problem they look for that answer and then simply write it down, never finishing the problem. For this scavenger hunt, I have "messed up" one element in each answer matrix. For this reason, I included a column on their answer paper for them to record which number is incorrect. This way, they are still forced to do the entire problem :) ANSWER KEY IS ALSO INCLUDED.
