Math Mammoth Grade 4-B worktext is the second student book for grade 4.

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.

Solid... with a few quirks
Very simple assembly. Was sturdy after all screws were tightened. Be aware that this is particle board so it will bubble up if it gets wet. I learned this the hard way by putting a plant on it that sweat through the pot and damaged it. I have 4 stars because two of the screws stripped in the home because of the cheap wood (I was even being careful not to yet m tighten them too much). Additionally, the screw hole covers were only cheap stickers that started peeling off within 24hrs. Otherwise the product was solid. If you don't mind exposed screw holes then those is a good deal. One other thing to note is that it only comes with 4 square backing pieces to cover 4 of the cubbies, not all 8. I wasn't expecting any but only 4 was a little odd.

Worth the money.
Was surprised with the way it was to be positioned, vertically. It’s perfect for where I wanted it. While it was different to my plan, I love it. It’s a good value for the price. It held bigger totes than I thought, it was easy to put together and seems to be well worth what I paid.
