Keith says:  As the digital nature of the classroom expands (google classroom, homework turned in digitally, interactive technologies to assist mathematics, online calculators, 2-d and 3-d graphing programs, etc), I find it necessary to be able to write on digital documents. The iPad with an apple pen is the most seamless solution.

It will be a great tool for me and my students to use in class and will aid in my work at home preparing for classes, responding digitally to students, and for grading work remotely.
