The Moore McGuffey series of readers covers a wide skill level span so it must be used at a slower pace than other readers. Readers have excellent discussion questions. You will want to use more reading material than what is included here to complete your program. This is an updated version of the Original McGuffey Readers that are published by Mott Media.
The First Reader is suitable for first and second graders, and for some third graders. The Second Reader should be appropriate for third and fourth graders, although some third grade level students might not be ready yet for book 2 because of the level of the comprehension questions. It also increases significantly in difficulty from beginning to end. Most fifth graders will be able to handle the Third Reader. It should be used for two or more years, being suitable for fifth through eighth or ninth grade levels. The Fourth Reader is appropriate for students in grades 10 through 12.
