Math Mammoth Grade 3-A student worktext covers addition, subtraction, graphs, the concept of multiplication, multiplication tables, telling time, and money. It is meant for the first half of grade 3. This student 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. This is the full-color version; in other words, the inside pages are in full color. Please note this is a student worktext and does not contain answers.
