This is a great activity to get your kids thinking as they look at a set of 5 exponential expressions and find the one that has a different value than the other four. When they are finished, they will solve a riddle using the letters in the answer boxes. Students will know if they have done the problems correctly if the riddle makes sense. This would be an excellent classwork or homework assignment. Please check out the preview to see the type of expressions that are in the activity.
This is one of the 11 activities in my Negative and Zero Exponents bundle which can be purchased for $4.00 at:
Common Core standards include both 8.EE.A.1 and HSN.RN.A.2, but the activity could be applicable to other grade levels as well.
Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 32 × 3-5 = 3-3 = 1/33 = 1/27.
Rewrite expressions involving radicals and rational exponents using the properties of exponents.
