Usually printed in 3 - 5 business days
Math Mammoth Grade 4-B worktext is the second student book for grade 4. This is the 2020 edition. In this part B, we first study division. The focus is on learning long division and using division in word problems. In geometry, we first review area and perimeter, and then concentrate on the topic of angles. Students measure and draw angles, solve simple angle problems, and classify triangles according to their angles. They also study parallel and perpendicular lines. Fractions and decimals are presented last in the school year. These two chapters cover only some of the basic operations with fractions and decimals. The focus is still on conceptual understanding and on building a good foundation towards 5th grade math, where fractions and decimals will be in focus. Please note this book is spiral (coil) bound. Some of the main features of the curriculum are: - It is mastery-oriented and organized into chapters by topics. Thus, in each chapter the curriculum concentrates on one theme and its connecting topics (such as place value, multiplication, or geometry). Each grade level typically contains 8-10 chapters. - The curriculum focuses strongly on conceptual understanding. - Visual models and exercises are used a lot. - Mental math and number sense are emphasized. - The curriculum is nearly self-teaching for many children, since the full explanations of concepts are included in the student books. Thus it requires fairly little preparation time from the teacher. - There are free videos that are matched to the curriculum. - The curriculum meets and exceeds the Common Core Standards. For the first half of 4th grade math, please use Math Mammoth Grade 4-A worktext (available separately at Lulu). Also available are the answer keys and a book containing cumulative reviews and chapter tests.
