Math Mammoth Grade 3-A worktext (2024 edition) is the student book for the first half of third grade math. In this part A, the main areas of study are: * addition and subtraction with mental math * addition and subtraction with regrouping (within 0-1,000); * writing an equation with an unknown for a word problem; * the concept of multiplication; * the multiplication tables; * telling time and working with time intervals; * counting coins and solving problems related to money. Features - Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the math, not just learn "HOW" to do it. - Concepts are often explained with visual models, followed by exercises using those models. These visual models can take the place of manipulatives for many children; however, it is very easy to add corresponding manipulatives to the lessons if so desired. - The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into its various aspects. This promotes conceptual understanding, as opposed to spiral curricula that often tend to jump from topic to topic too much. - There is a strong emphasis on mental math and number sense. - The curriculum requires very little teacher preparation, which is a big help to most parents. :) - The curriculum has no separate teacher's manual nor is it scripted. The introduction to each chapter has some notes for the teacher concerning the material in the chapter. All the instruction is written directly to the student in the worktext, and there also exist accompanying videos where you can see Maria herself teach the material. - After each chapter introduction, you will find a list of Internet links and resources (games, quizzes, animations, etc.) that can be used for fun, illustrations, and further practice. - For multiplication tables and division facts, you can use our online practice program (free). A companion to this book, Math Mammoth Grade 3-B worktext, covers the second half of 3rd grade math (available separately). Also available are the answer keys and a book containing cumulative reviews and chapter tests.
