BIG FAT NOTEBOOKS are a series of study guides for middle school students or anyone who would like a refresher in Science, English Language Arts, American History, and World History. Created by the editors of Brain Quest, each of the 5 study guide books covers one main topic at the middle school level. Within each book, you will find: Important information highlighted, vocabulary in yellow, definitions colored in green, and blue for important people, places, dates, and terms. Illustrations and charts for deeper understanding (plus they break up the words and make it easier for visual learners). Quizzes at the end of each section with the answers on the following page. A must-have for home schoolers. These books provide so much potential: you can use them as a quick reference, use them as a spine to stem from, or use them as review! Books are pre-owned and in great condition. Three of the books have minimal wear on corner covers, and the science book has the first four pages slightly bent. Please see pixs. Questions?
