We continued to work on the webquest today in the computer lab. Most students are now finished with Zoo Challenge 1. They could “buy” more animals with a million dollars than many of them expected! We learned how to use a formula inside a cell, how to paste a formula from one cell to another, and how to find the sum of a column in Microsoft Excel.

We will return to class tomorrow to finish the Data Analysis chapter. We will do two more sections and then have a test on Friday. The work I assigned last week is due tomorrow. Here is a summary of what I have planned for this week:
