Math Mammoth Grade 3-A Worktext is the student book for the first half of grade 3, and part of the Math Mammoth Grade 3 complete curriculum. This book covers addition, subtraction, word problems, graphs, the concept of multiplication, multiplication tables, telling time, and money. The worktext contains both the necessary instruction and the problems & exercises (the 'text' & and the 'work'; thus a \"worktext\"), and is fairly self-teaching. The curriculum meets and exceeds the Common Core standards. Please note this is a student worktext and does not contain the answers. The answer key book is available separately. | Math Mammoth Grade 3-A Worktext by Maria Miller, Paperback | Indigo Chapters
