Welcome to the MS Computer Lab Blog!
The objective of our blog is to share information about how we integrate our technology curriculum into the subject area curriculum. The foundation of this effort is the methodology of team teaching the lessons with the Middle School subject area teachers. Each post describes a particular lesson, the software used, some of the skills that were targeted, and the number of days that were spent in the lab.

Probability and Excel
The 6th grade Math students used the randbetween function in Excel to generate different sample sizes of random numbers from one to three. They used conditional formatting to get an idea of the percentages of each number. In addition, they used the countif function to tabulate the frequency of each number and then graphed the breakdown in a pie graph. The students were able to compare the graphs and see that as their sample size increased the probability that a certain number would be chosen got closer and closer to 33.3%.
