I work at a school that has incorporated iPads from 6-12. For the most part this has been a wonderful experience. I had the opportunity to show of Numbers to eighth grade Science students. They were able to easily follow the basics inputing numbers, creating rows and columns, and working basic mathematical operations. I have one complaint about Numbers, it does not do regression. We even explored creating scatterplots and can use functions find the slope and the y intercept of the data, but we couldn't add a regression line. Sure we could plot data based upon the calculated information however that isn't showing a line of data. Would it be too much to ask for this functionality? Math classes would enjoy it as much as Science classes. It would be great not to have to find another app.
