These extraordinary workbooks each provide dozens of on-grade-level reading comprehension passages. The passages include fiction, nonfiction and poetry. Each passage is followed by a number of multiple-choice questions. The questions test and provide practice in reading comprehension skills, both for literal comprehension and critical-thinking skills. An open-ended question follows nearly every passage. These questions provide practice in both reasoning skills and composition. These are very substantial books-110 to 250 pages each-with hours and hours of reading assignments and practice questions in each. The Grade 1 book includes extensive illustrations. The Grade 2, Grade 3 and Grade 4 books also include some illustrations, to help hold younger students’ attention. Teacher Editions provide suggestions for use, correct answers to multiple-choice questions, and suggestions for appropriate responses to open-ended questions. Great tools for home schooling as well.
