You may include strategies that did not work if they are fully explained, and the reasons they did not work are explained. Included in this section should be charts, lists, graphs, pictures or other necessary diagrams. Explanation of what you did to solve the problem is good but you may have only explained one strategy. You may have included diagrams, charts, lists or graphs, however, they may be incomplete or unlabeled. You may not have explained enough detail to satisfy the requirement.
Explanation is weak.
Strategy used may be unexplained. Little effort is shown. Explanation is poor. Little or no effort is shown. The solution is appropriate, and all mathematical work is shown.
