My unit is very much centered in real-world situations, which is a Best Practice idea. Showing how math relates to students’ lives will not only make them more interested in the math, but also help them learn and remember the material better, for they will have a personal connection to it and understand its purpose. In addition, Best Practice encourages collaborative work in mathematics to help students learn to exchange ideas with one another and to allow students of mixed abilities to learn how to help each other. At several points in my unit, students will be put in heterogeneous group so that they can experience those two principles.
