"Math Paper is by far the best option I’ve seen for doing math work on the iPad! Math Paper won’t do calculations or graphs, but it provides all the tools needed to do everything from basic computation to complex algebra. Math Paper has been developed with the principles of UDL in mind, so it’s a tool that can be used effectively and independently by anyone, including individuals with motor challenges or cognitive processing issues. Accessibility and ease of use have been addressed successfully.
Math Paper cost: $19.99. Paul Hamilton notes in his blog that this is an exceptional app and is worth the cost.
