Welcome to the 2022 edition of Primary Mathematics: same pictorial-to-abstract mastery-based methodology, but easier to use and more appealing to students. A year’s worth of math instruction is divided into two semesters with a textbook and teaching materials for each semester. This 1B textbook contains a variety of exercises presenting the math lesson, from pictorial to abstract, as well as the “Practice on Your Own” pages that the student does independently for Grade 1 Semester 2. Primary Mathematics textbooks are consumable and designed to be used in conjunction with the Primary Mathematics Home Instructor Guide (for one-on-one instruction) or Primary Mathematics Teacher Guide (for classroom-oriented instruction) that match its grade level and semester. Answer Key is located in the two teaching guides. 226 pages, softcover. Grade 1.
