Chance Game Design: Math, Data, and Probability

Grade 6Math1 days
In this project, 6th-grade students design a fair game of chance using probability and data analysis. They collect and analyze data to assess the fairness of their game, using measures of central tendency and ICT tools to interpret data and compare experimental probabilities to their theoretical model. Students present their game and data findings to demonstrate their understanding of probability concepts and game design principles.

Teacher-Provided Standards

MA6.DAP.1
Primary
Solve problems by collecting, selecting, processing, presenting and interpreting data using ICT where appropriate; draw conclusions and identify further questions to askReason: This standard directly addresses the data collection, analysis, and presentation aspects of the project, as well as the use of ICT tools.
MA6.DAP.2
Primary
Describe and interpret results and solutions to problems using mode, medium, mean, rangeReason: This standard directly aligns with the project's requirement to use measures of central tendency and range to analyze game data.

Common Core Standards

CCSS.MATH.CONTENT.7.SP.C.5
Supporting
Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.Reason: This standard supports the fundamental understanding of probability needed to design a game of chance.
CCSS.MATH.CONTENT.7.SP.C.6
Primary
Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability.Reason: This standard is directly relevant as students will collect data to determine the fairness (probability) of their game.
CCSS.MATH.CONTENT.7.SP.C.7
Secondary
Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.Reason: This standard extends the project by having students compare their theoretical probability model with the actual results from playing the game.

Entry Events

Events that will be used to introduce the project to students

Chance Lottery

**"Chance Lottery"**: A seemingly fair lottery is conducted in class, but the results disproportionately favor certain "players." Students investigate the lottery's mechanics to uncover hidden biases or manipulated probabilities. This experience introduces the concept of fairness in a personal, engaging way.

Mystery Box Challenge

**"Mystery Box Challenge"**: A locked box is presented. Inside is a working game of chance, but students can't see it. They must ask questions and perform probability experiments (using provided materials) to guess the game's rules and fairness before it's revealed. This sparks curiosity and connects probability to real-world deduction.

Design a Carnival Game

**"Design a Carnival Game"**: Students are tasked with designing a new carnival game, including the rules, payout structure, and an analysis of the game's profitability. They must consider the probability of winning and the house edge to ensure the game is both fun and financially sustainable. This blends creativity with practical math skills.
