Inequality Mobiles

These photos are a couple of the Inequality Mobiles my students created.  We had a lot of fun.  Each student was assigned an inequality at random.  They had to work out the inequality, graph it, and use it to create a mobile.  The mobile is created using a hanger, string, paper and tape.  The purpose is to give the students time to focus on one problem.  This is a favorite project of mine because it’s fun, it allows students to be creative in a subject that doesn’t always support creativity, and it allows students time to think about why they are solving problems the way they are and ask important questions.
