Today's Learning Goal: (G6, U6, L15)
Describe (orally) the values that result from evaluating expressions in which a fraction is raised to a power.
Determine whether a given value is a solution to an equation that includes an exponent.
Evaluate expressions that have a variable, an exponent, and one other operation for a given value of the variable, carrying out the operations in the conventional order.
Today's Materials:
Laptop
Laptop charger
Pen/Pencil/Paper/Expo Marker (optional)

How did you make use of the meaning of operations and exponents in each activity?
How did thinking about the meaning of operations and exponents help to find the value of in the activity with the equations?
Was there anything you learned in the first activity that helped you with the second activity?
Match each equation to a solution.
