PowerPoint lesson on applying rational numbers. Includes a notes page as well. This lesson is the last lesson I teach after my unit on rational numbers. It is a culmination of all four operations with rational numbers and is a more student/group centered lesson. I do little to no teaching as an entire group, but rather spend most of my time helping individual groups. It is only four word problems, but they are challenging and take most groups an entire period to figure out. Calculators might be appropriate for number three and four. There are also review whiteboards at the end of my lesson if you have extra time. My PowerPoints are completely editable so please change them to suit your needs. Please feel free to let me know if I can assist you in any way or if you ever encounter any problems with my PowerPoints.
