McGraw Hill

McGraw Hill has a wealth of information. In the digital content some things are at the Chapter Level, and some things are at the Individual Lesson Level. There are tests made for every chapter and every test available within the Chapter level or you can find them in the assessment suite. All tests and quizzes are able to be assigned as is, or can be edited as needed. 

McGraw Hill has included Page Keeley probes at all levels to encourage students as to why they are learning each set of materials. Depending on the grade level, these questions, or probes, can be found in different places.
