Students must provide a written explanation of the thought process used to build a solution for each
question. Students are encouraged to provide charts, diagrams, and graphs, if necessary and must
always include mathematical calculations within the written work. All solutions should be written in
complete sentences and should provide a logically sound argument defending how they got to their
solution. All outside of class problems will count as a quiz grade and you are encouraged to seek
help from me, your parents, and peers. The in class problems will count as a test grade showing how
you can attack a problem on your own.
