idea of graphing weekly salaries based on educational levels, from not finishing high school up to a doctorate; represent it with a pictograph using play money; developing questions for different grade levels to answer based on the data in the graph.
An idea from a mid-Michigan high school. Each teacher adopts a bathroom stall. He/she decorates with holiday motifs, inspiring quotes, study material, jokes, etc. The bathrooms have never been so tidy and respected.
