**Teacher Testimonial:** Math Shadows is an activity lesson that gives students the opportunity to use some of their mathematical knowledge in the real world. They work in groups and walk around campus applying their math skills in order to find the heights of a tree, a basketball hoop, and a flagpole. A worksheet is included which allows the teacher to personalize the activity for his students by choosing other objects that are found on his own campus. Students enjoy the change of pace and the chance to work together.
