The final report is complete but has a few mathematical errors. The explanations are correct but could have been stated more clearly. Diagrams are not used to clarify the explanations. 2 Students make a balance and collect their data to explore inverse variation. The balance and data collection are done correctly, but the work to explore rational expressions has some serious problems involving the data collection, the calculations, and the variable expression written.
Students attempt to write a report, but it is incomplete and the explanations given are confusing.
1 Students have difficulty making a balance and collecting data for exploring inverse variation. They do not proceed beyond this point in the experiment. Students are encouraged to speak with the teacher as soon as possible to review their work and to make a new start on the project. Playing the Game 4 Students play the game and develop strategies for winning. They give a clear and interesting oral report to the class and demonstrate successful strategies for winning.
