Math Mammoth Grade 5 complete curriculum consists of two student worktexts (A and B), a separate answer key for each, chapter tests and an end-of-year test, cumulative reviews, and an easy worksheet maker (Internet access required) to make extra practice worksheets when needed. They are aligned to common core standards.

The two books (worktext part A and part B) deal with

  • whole numbers and their operations
  • prime numbers and factorization
  • simple equations
  • problem solving with bar models
  • place value with large numbers and the judicious use of calculator
  • all operations with decimals
  • statistics and graphing
  • all fraction operations
  • geometry: classifying and drawing triangles & quadrilaterals; calculating the area of rectangles, triangles, parallelograms, and compound figures; surface area and volume of rectangular prisms
  • introduction to ratios

Please see the sample files to see the table of contents and a complete lesson list.

Some main features of the Light Blue Series books are:

  • focuses on understanding of mathematical concepts
  • uses clear explanations and lots of visual aids
  • mastery oriented: concentrates fairly long on a topic, with fairly few topics per grade
  • emphasizes mental math and developing number sense
  • very little teacher preparation needed



Math Mammoth Grade 5-A Worktext comprises a complete math curriculum for the first half of fifth grade mathematics. The fifth grade is time for fractions and decimals, in particular. In part 5-A, we study decimals in depth and with substantial detail. Students also deepen their understanding of whole numbers, learn much more problem solving, and get introduced to the calculator.

The year starts out with a study of whole numbers, their operations, and problem solving. Students get to review multi-digit multiplication and long division. Then we study equations with the help of a balance and bar models (simple diagrams). The main idea is to get students used to the idea of an equation and what it means to solve an equation.

In the second chapter, the focus is on large numbers and using a calculator. This is the first time a calculator is introduced in Math Mammoth complete curriculum—thus far, all calculations have been done mentally, or with paper and pencil. I want students to learn to be critical in their use of the calculator—use it with good judgment. Every exercise where calculator use is to be allowed is marked with a little calculator symbol.

The fourth chapter is about decimals and their operations. It is a long chapter because now is the time to learn decimal operations well. It is assumed that the student already has a solid foundation for decimal place value, as taught in Math Mammoth 4th grade curriculum. That is the true means of preventing common misconceptions, or students resorting to rote memorization of the decimal operations.

Math Mammoth Grade 5-B Worktext comprises a complete math curriculum for the second half of fifth
grade mathematics. Fifth grade focuses on fractions and decimals, in particular. In part 5-A, students have
studied the four operations with whole numbers, large numbers, problem solving, and decimal arithmetic.
In this part, 5-B, we study graphing, fraction arithmetic, and geometry.

This book starts with chapter 5, where we study graphing in a coordinate grid, line and bar graphs, and
average and mode. Today’s world has become increasingly complex, with lots of data in the media, so our
children need a good grasp of graphs to be able to make sense of all that information.

Chapter 6 is about the addition and subtraction of fractions—another focus topic for 5th grade, besides
decimals. Students learn to add and subtract unlike fractions, using the technique of first converting them
to equivalent like fractions. In chapter 7, we study the multiplication and division of fractions (division
only in special cases), relying first on visual models, and then proceeding to the abstract shortcuts.

Chapter 8 takes us to geometry, starting with a review of angles and polygons. From there, students will
learn to draw circles, to classify triangles and quadrilaterals, and the concept of volume in the context of
right rectangular prisms (boxes).

This product also includes an HTML page that you can use to make extra practice worksheets for computation, and a list of helpful Internet links for each chapter.

This curriculum has been easy to use and simple to implement. It is a mastery program instead of spiral, so my child was able to firmly grasp the concepts, and then we did the mixed reviews at the end of each chapter to make sure retention occurs. I [...]

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
