Learning goals: Teacher Facing Generalize a process for finding the surface area of a cube, and justify (orally) why this can be abstracted as $6 \boldcdot s^2$. Interpret (orally) expressions that include repeated addition, multiplication, repeated multiplication, or exponents. Write expressions, with or without exponents, to represent the surface area of a given cube.
