Instructional Ideas

Have students create their own "cheat sheet" as a review of important material, whether or not they get to use it for an exam. Use the print or share options to compare with a partner. 

This app would make a good reference tool in the classroom, or for an advanced math student. 


Classroom Considerations

Consider dedicating one device in your classroom to reference tools such as these.
