Learning goals: Teacher Facing Interpret hanger diagrams (orally and in writing) and write equations that represent relationships between the weights on a balanced hanger diagram. Use balanced hangers to explain (orally and in writing) how to find solutions to equations of the form $x+p=q$ or $px=q$.
