Publisher's Synopsis
Math Mammoth Grade 4-B worktext is the student book for the latter half of grade 4 mathematics studies. This is the full color version. Being a worktext means that the book contains both the instruction and all the exercises and problems.
In this book, Math Mammoth Grade 4-B, we first study division. The focus is on learning long division, using division in word
problems, and studying factors and divisibility.
In the chapter on geometry, we first review area and perimeter, and then concentrate on the topic of
angles. Students measure and draw angles, solve simple unknown angle problems, and classify triangles
according to their angles. They also study parallel and perpendicular lines.
Fractions and decimals are presented last. These two chapters teach and practice only some of the
operations with fractions and decimals. The focus is still on building conceptual understanding of these
concepts as a foundation towards 5th grade, when fraction and decimal arithmetic will be in focus.
