With more online graphing sites becoming free, I feel the tablet computer (ipad or other) will have a greater influence on the type of graphs we generate.
As of now, I have been reliant upon the TI 83/84 calculator for graphing purposes. And believe me, its a great device; however it does not suit all my graphing needs.
First and foremost, it is a pain to graph in more than one variable. The graphing program at desmos.com can graph in two variables, in polar and function forms; which makes graphing circles and ellipses easy. Desmos.com works with the ipad in that it does not use flash. It allows for parameter setting. I love it!
I also see the iPad influence data charts (pie, line, bar). We can generate spreadsheets to model budgets or cost. Graph them and learn to analyze.
I will be developing a lesson using the Numbers app to model a sample cost analysis on diapers. Its how I can integrate math into real life. The "essential" question for that lesson: How much will I spend in diapers a month, a year? We will also include rent, food and entertainement costs.
The video clip below is some of my students using the ipad to graph the pacman ghost. I gave them 3 to chose from. A basic pacman ghost which gives them a proficient grade, a hello kitty version of the pacman ghost which gives them an "approaching exemplary" grade and the boba fett pacman ghost which gives them an "exemplary" grade
Sorry. I changed the status. Forget to check the appropriate button. Hope you can now see it. Below is the last class of today that were using the ipads. They were freakishly quiet. Don't know why, other than they were really into the assignment. The noise level picked up after they got stuck on the assignment.
Yep, we can see them now and they are really awesome for our replication concept. The last one where your kids were "freakishly" quiet is testament to getting them genuinely engaged. The graphic ideas that you can now explore have been expanded as far as the mind can see. Go for it. Most interested in seeing your Lesson on Numbers App for cost analysis. I'm thinking you might want to share that with the Community at large so we can all benefit from your creativity.
You could also post your videos in the IPad Group. I bet there are teachers in that group who would love to see how you have expanded the IPad in your class.
Keep up good work.
