Teacher will help students discover what a zero or a half credit score will do to their mean (grade) using Unifix Cubes. Using a calculator, students will calculate and compare the means.
 
 
You will need Unifix cubes, a "hypothetical" list of grades, and either a TI-80, TI-82 or TI-83 calculator.
 
 
Build a model using Unifix cubes to demonstrate the concept of averaging.
 
 
Use their "hypothetical" list of grades to calculate their numerical average or grade.
 
Re-calculate their average with a zero or a half-credit score factored in to discover the impact on their numerical grade.
 
Using the graphing calculator, compare the results of their grade averages with and without a zero.
 
Contrast their graphing results with other students in the class.
 
Calculate the class average.
 
 
Calculate the average temperature for a month of the year.
 
Calculate the average rainfall for a month in the fall and a month in the spring and compare.
 
 
Use the calculator to average physical fitness trials in your class - For example, calculate the average time of your class in the mile run or the average number of sit-ups completed.
 
Calculate the average number of students participating in school "hot lunch" - For example, compare lunch counts to different types of food served.
