This 19 page Halloween unit begins with a discussion of teaching mathematics for mastery, through problem solving strategizing. Next are a few pages you might share with students either by copying, or via a SmartBoard or Promethean Board. These are the basis of the thought process for students. Finally, there are 10 Halloween-Themed word problems with adorable graphics, and plenty of room for students to draw, write, explain, and defend their mathematical thinking. If used as described, ten problems would take ten lessons to complete.
