Do your students have an appetite for math or does math make them sick to their stomach? In middle school we see both ends of this spectrum. In searching for a proportions lesson I stumbled upon some snack food that will help feed our students in math classes. The tool I'm about to share is really cool and engaging BUT the way I found it can give any teacher power to find new ways to engage students in math and all other subjects. (So stayed tuned to the bottom and find out a powerful tool to help find ideas for ALL teachers)
http://www.mathsnacks.com/ that is produced by New Mexico State University. Math Snacks have engaging animations, a learner guide and a teacher guide with each math concept.
Take a look at this math snack on ratios and proportions. http://www.mathsnacks.com/badDate.html
I know that kids will love this video and it gives them an opportunity to experience ratios and proportions in a new light. This particular math snack comes with a learner's guide that will them from the examples used in the video to other real life applications. The teacher's guide is a detailed lesson plan with directions, answer key and extension activities. Explore and check out this website. It is still in development and currently has 9 available snacks and plans to have at least 20 by next school year. It is sure to satisfy some of your most reluctant student's appetite for math.
