Develop Understanding
Today's Learning Goal:
  • 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)
