Game Idea & Design
4 pts

Excellent

Students create a fully functioning game that students can play. Game is easy to play and slightly difficult to win. The idea for the game is highly original and creative.
Good

Students create a game
that students can easily play, but minor problems with design or construction are evident. The idea is creative and fun.
Fair

Students create a game that students can play, but it is too easy to win. One or more significant problems of design or construction are evident. The idea behind the game is not original.
Poor

Game is poorly made and not sturdy enough to hold up to the carnival. Game is too difficult for others to play, requiring game designers to have too large of a role in "playing" the game.
Rules of the game
4 pts

Excellent

Instructions for the game were visible and easy to read, and contained all required elements. The game can be played without help.
Good

Instructions are included for the game and contained all required elements. Game can be played with minimal interaction by the game creators.
Fair

Instructions are written but unclear, with one or more of the required elements missing. A verbal description of the game is necessary for students to be able to play.
Poor

Students did not create a rules poster for the game.
Experimental probability
4 pts

Excellent

Students collected and included data for at least 50 test trials in their report, and provided an accurate analysis of the experimental probability of winning and losing with justification and explanations.
Good

Students collected data for at least 50 test trials and provided an accurate analysis of the experimental probability of winning and losing with justification and explanations.
Fair

Students collected data from at least 50 test trials but did not provide accurate experimental probabilities of either winning or losing.
Poor

Students did not collect data from their test trials and/or failed to provide accurate experimental probabilities of winning and losing.
Profit Made- Experimental
4 pts

Excellent

Students correctly calculated the profit from the game, including all expenses and revenue based on experimental probability data. Gives a complete explanation of how profit was calculated.
Good

Students correctly calculated the profit from the game based on experimental probability data, but fails to explain how it was calculated.
Fair

Students inaccurately calculate the profit from the game based on experimental probability data due to 1 or 2 errors in calculation.
Poor

Students make more than 2 errors in calculation and fail to explain profit as it relates to experimental probability.
Theoretical probability
4 pts

Excellent

Students correctly calculated the theoretical probability for each outcome for the game by including the sample space, AND compares it to the experimental probability.
Good

Students correctly calculated the theoretical probability for each outcome for the game by including the sample space, but does not provide a comparison to experimental data.
Fair

Students calculated the theoretical probability for the various outcomes of the game, but based their work on an incomplete sample space, leading to errors.
Poor

Students inaccurately calculated the theoretical probability for the various outcomes for the game due to one or more major errors in sample space or computations.
Profit Made- Theoretical
4 pts

Excellent

Students correctly calculated the expected profit from the game, including all expenses and revenue based on theoretical probability. Gives reasonable projected values for expected profit from the entire carnival, and explains how it was calculated.
Good

Students correctly calculated the expected profit from the game based on theoretical probability and gives reasonable projected values for expected profit from the entire carnival, but fails to explain how it was calculated.
Fair

Students inaccurately calculate the expected profit from the game based on theoretical probability due to 1-2 errors in calculation. An attempt was made to include projected profit for the carnival.
Poor

Makes more than 2 errors in calculation and fails to explain expected profit as it relates to theoretical probability. Fails to include projected profit for the carnival.
"Selling" your game
2 pts

Excellent
Good
Fair

Addresses why people would want to play the game and why it should be in the carnival.
Poor

Explains why people would want to play the game or why it should be in the carnival, but not both.
Workload
2 pts

Good
Fair

The workload is divided and shared equally by all team members.
Poor
