1. If needed, use the links above to review the exponent rules for multiplication.

2. Ask each student to take out a sheet of notebook paper. Open the Exponent Foldable presentation and guide students through creating a foldable to keep up with all of the rules of exponents.

3. Use masking tape to make a "human fraction bar" on the floor. Ask for or call on eight students to volunteer. Direct five to stand above the line and three to stand below the line. Remind students that when you have things on top and bottom that match, they cancel out. In other words, something divided by itself is equal to one, and multiplication by one does not change the product. So pull pairs of students away from numerator and denominator until all denominator volunteers are gone.

4. Ask students to look at what remains. See if they can deduce a rule that would describe how we went from five people on top and three people on bottom, to two people on top only. They should realize that 5 - 3 = 2. That is the rule for exponents and division (when dividing powers with the same base, subtract the exponents).

5. Open the Exponents and Division presentation (adapted from http://teachers.henrico.k12.va.us/math/HCPSAlgebra1/module7-2.html). Go through each slide with the students and have them take notes, work out examples, and add the following rules to their foldable: division, zero exponent, and negative exponent.
