I am a high school Mathematics teacher. One of my students has cerebral palsy and has difficulty with tasks that require fine motor skills. She uses an iPad for a good deal of her work in my class and in her other classes. I have been searching for an app that she can use to show her work as she completes assigned problems. Ideally it would be similar to EQ Editor, but with the added functionality of being able to show multiple steps at a time. There are lots of apps in the App Store that will solve the problem for her, but that's not what I'm looking for at all. I'm hoping that these an app out there that will be helpful, but I haven't been able to find it despite many hours of searching (and purchasing apps that I thought would help, but finding them falling far short of my needs and expectations). Any help would be much appreciated. Thank you!
