When students reach middle school, they must work on a daily basis with integers. If they haven’t mastered them by the time they reach high school, they end up in trouble.Integers are the 'verbs' of algebra-if you don’t understand the verbs, you can’t do much of anything. This workbook shares a decade of research and closes a crucial gap that prevents many students from understanding integers.The system uses a sea-level chart that is so successful that even younger children can use it to master algebraic concepts. In fact, its creator, a longtime math and science teacher, used the system to teach his daughters how to manage the addition of integers before introducing it to his students. At the time, his daughters were ages five and seven.The system presented in this guidebook is an important resource for parents, teachers, and students. Give students a fighting chance to perform operations on integers using the research-based method presented in The Verbs of Algebra.
