Teacher-Provided Standards
Entry Events
Events that will be used to introduce the project to studentsSchool Survey Challenge
**The Great School Survey Challenge:** The principal needs data to make important decisions about the school (e.g., recess time, lunch options). Students design and conduct surveys to gather data, then analyze and present their findings to the principal. This gives students ownership over the data collection process and allows them to see how statistics can impact their own school environment.Predicting the Future
**Predicting the Future:** Introduce students to the concept of prediction by having them analyze past weather data or sports statistics. Students use this data to make predictions about future events, discussing the limitations and uncertainties involved. This encourages critical thinking and highlights the relevance of statistics in everyday life.The M&M Experiment
**The M&M Experiment:** Provide each student with a bag of M&Ms (or another type of candy with varying colors). Students count the number of each color, create graphs to represent the data, and calculate the probability of picking a specific color at random. This simple, engaging activity provides a concrete introduction to data analysis and probability while catering to students' interests.Portfolio Activities
