Probability Investigation
	Poor 1 pts	Fair 2 pts	Good 3 pts	Excellent 4 pts
Step I Choose carnival game Total 20 points	Poor A written proposal was not submitted on the necessary items: game description, materials needed, summary of rules, and a plan for calculating probabilities.	Fair A written proposal was submitted that includes some of the required information but was incomplete: game description, materials needed, summary of rules, and a plan for calculating probabilities.	Good A written proposal was submitted that includes all the necessary items with some insight into the actions of the group: game description, materials needed, summary of rules, and a plan for calculating probabilities.	Excellent A written proposal was submitted that includes a thorough information regarding: game description, materials needed, summary of rules, and a plan for calculating probabilities.
Step II Build game Total 10 points	Poor Students did not create a game but could not be played.	Fair Students created a game, but it could not be played the entire carnival.	Good Students created a game that other students can play. There were slight oversights, but overall the game could be played.	Excellent Students created a fully functional game.
Step II Rules of the game Total 10 points	Poor Students did not create rules for the game.	Fair Instructions are written but unclear and a verbal description of the game is necessary.	Good Instructions are included for the game and it can be played with minimal interaction by the game creators.	Excellent Instructions for the game were visible and easy to read. The game can be played without help.
Step III Empirical probability Total 20 points	Poor Students did not collect data and or provide an empirical analysis with justification and explanations.	Fair Students collected data but did not provided a correct empirical analysis with justification and explanations.	Good Students collected data and provided an empirical analysis that was somewhat accurate with justification and explanations.	Excellent Students collected data and provided an accurate analysis of the empirical probability with justification and explanations.
Step III Theoretical probability Total 20 points	Poor Student did not calculate the theoretical probability for the various outcomes of the game	Fair Students calculated the theoretical probability for the various outcomes for the game, but it was inaccurate.	Good Students calculated the theoretical probability for the various outcomes for the game but there were a few errors.	Excellent Students correctly calculated the theoretical probability for the various outcomes for the game.
Step III Expense, revenue & profit Total 20 points	Poor Student did not calculate the expected profit from the game.	Fair Students calculated the expected profit from the game but had several errors or missing elements.	Good Students calculated the expected profit from the game but had a few errors or missing elements.	Excellent Students correctly calculated the expected profit from the game, including all expenses and revenue.
