This app is a powerful graphic calculator that shows mathematical equations in 2D or 3D. It is simple to use and easy to edit.
Pro: Easy to enter and/or edit equations and visualize those equations. For students in Algebra, it answers why they need to know or learn Algebra. Gives ideas of the future of their mathematical education. The images can be copied, emailed, or saved into the photo library. There can be up to 6 equations visualized simultaneously in both 2D and 3D.
Cons: Mainly for students in Algebra and above, therefore many elementary students will not have the need to use them. Now you must specify x, y, and z. Also, the dependent variable must be specified.
Using in Education: I think it would be a great tool to use in the classroom for math classes that use graphs. Helps the students to visualize the problems they are working through. Great for visual learners!
I like how this app allows you to see your graph in 3D and rotate the graph to see it from all angles. I enjoyed experimenting with different graphs in this app and I think students could benefit from being able to interactively plot multiple graphs and view them from various angles. I could see this as being a wonderful asset to a math classroom, especially when students are beginning to learn how to graph equations.
