Learning goals: Teacher Facing Coordinate tape diagrams and equations of the form $px+q=r$ or $p(x+q)=r$. Create a tape diagram to represent an equation of the form $px+q=r$ or $p(x+q)=r$, and use it to solve the equation. Identify equivalent equations, and justify (using words and other representations) that they are equivalent.
