Last Friday I was fortunate enough to have the time, energy, and forethought to plan a lesson that went off swimmingly and I want to share its pros and cons here
My students have been honing their graphing, solving, and analyzing skills since returning from Winter Break. I noticed a severe lack of comfort in manipulating fractions as well, so I wanted them to be exposed to that as well. In order to bring it all together, I had the of idea of letting the students create graphs on graham crackers using icing. If you take a graham cracker and rotate in 45 degrees in either direction, the holes perfectly line up to create a grid. It was wonderful.
I explained it to my students exactly this way:
Level Two consisted of systems involving fractional coefficients or negative numbers. They needed two graham crackers to create (an added incentive).
Level Three consisted of a system of linear inequalities involving shading (translation: more icing). It was quite difficult and only one student achieved it. Unfortunately, he had to go to his next class before graphing it on the graham crackers.
Overall the activity was a great success - almost all students were working (even those who had previously given up). I was able to increase the skill of many and reinforce the need to come to tutoring for some. I would highly recommend using this lesson if you can in the future.
