Learning goals: Teacher Facing Apply the distributive property to generate algebraic expressions that represent a situation involving adding or subtracting a fraction of the initial value, and explain (orally) the reasoning. Coordinate tables, equations, tape diagrams, and verbal descriptions that represent a relationship involving adding or subtracting a fraction of the initial value. Generalize a process for finding the value that is “half as much again,” and justify (orally and in writing) why this can be abstracted as $\frac32 x$ or equivalent.
