Grade: 7

 

Sample Activities:

 

·        Students examine weather data for their community from previous years, and then use their analysis of the data to predict the weather for the upcoming month. They compare the actual results with their predictions after the month has passed and then use the comparison to determine ways to improve their predictions.

 

·        Using data from previous years, students determine the number of times their favorite professional football team scored a number of points in each of six ranges of scores (0-5, 6-10, 11-15, 16-20, 21-25, and 26 or more). They determine the fraction or percentage of games the score was in each of those ranges and make a spinner whose areas are divided the same way. Each Friday during football season, they spin their spinners to predict how many points the team will score and who will win the game. Toward the end of the season, they discuss the success or failure of their efforts and the probable causes.
