At this point in the unit, students have learned the conceptual reasoning behind all the rules or laws of exponents. Before combining the use of multiple rules into one problem, this lesson allows students to practice recognizing what rule should be used in a single problem. We’ll practice this with a dice game and some additional ByteLearn practice. You can expect this lesson to take one `45`-minute class period.
ByteLearn gives students targeted feedback and hints based on their specific mistakes
Students will be able to simplify exponential expressions using the rules of exponents.
At the beginning of class, pass out copies of the reference sheet for each student. You can use the slideshow to display one rule at a time in the front of the classroom.

You’ll review each exponent rule, pointing out specific differences in each. For example, I always like to explicitly remind students that when powers are multiplied, we add the exponents. But, when a power is raised to another power, that is when we multiply the exponents. Spend about `5-10` minutes reviewing each of the exponent rules and their examples on the reference sheet.
*Teacher tip: You can print out a poster size version of the reference sheet to use as an anchor chart in your classroom!
Have students partner-up. You can assign partners or have them choose themselves. Each pair gets `1` half-sheet of “Exponents Review Dice Game”. Each student gets `1` half-sheet of “Student Answer Sheet”. There is an additional Teacher Answer Key. Keep that to check student answers as they finish.
After you’ve completed the examples with the whole class, it’s time for some independent practice! ByteLearn gives you access to tons of exponents activities. Check out the online practice and assign to your students for classwork and/or homework!
