#### Product Description:

This is a complete Grade 5 math curriculum that meets and exceeds state standards. In worktext A the 4 chapters cover in order: continuation of decimals, adding or subtracting fractions, multiplying or dividing fractions, and geometry Instruction that is written directly to the student and requires very little teacher preparation. These worktexts are consumable and each student will need their own worktexts. Included in each worktext is a user guide for parents to utilize as problems and issues arise. Helpful, free, lesson videos are provided on the publisher’s website along with a practice worksheet generator. 200 pgs, pb. ~Rebecca

#### Publisher Description:

Math Mammoth Grade 5-B worktext (Light Blue Series) is the student worktext covering the second half of fifth grade math in the Math Mammoth curriculum. This is the 2023 edition.

The books starts out with chapter 6, where we study multiplying decimals by decimals, dividing decimals by decimals, and conversions between measuring units.

Chapter 7 covers the addition and subtraction of fractions, and chapter 8, the multiplication and division of fractions.

Chapter 9 is about geometry. Students learn to classify triangles and quadrilaterals, and study the concept of volume in the context of right rectangular prisms.

This edition provides the same great mastery approach to math that we know and love from Math Mammoth. The revised edition of Grade 5 has streamlined lessons, making some lessons optional, and has rewritten entire lessons in chapters 1, 2, 5, and 9. The lesson concerning circles has been removed and longer lessons in chapter 1 have been made into two separate lessons. These revisions have been made to help create a more focused presentation. The same four components (2 worktexts, test booklet, answer key) are specific to this edition. Areas of study in Grade 5 include: the four operations with whole numbers, decimals, and fractions; along with statistics, graphing, problem solving, and geometry. ~Rebecca

Category Description for Math Mammoth:

Theres a whole lot to like about this well-conceived and inexpensive math program. The main features of this program, according to author Maria Miller, are:

• Focus is on conceptual understanding rather than rote problem-solving
• Teacher instructions are right in the book; no need to buy a separate teacher book
• Clear explanations are written for the student, so the lessons are virtually self-teaching
• Lessons use lots of visual and pattern exercises
• Mastery oriented:concentrates on each topic for a long time studying fewer topics per grade than with spiral
• Emphasis is on mental math and number sense
• Very little teacher preparation is required
• Content aligned to Common Core Standards

These are all valid claims and sum up this approach nicely. Its linear approach is similar to that of the MCP Math program. Topics are introduced, studied in depth, then the student proceeds to the next topic. Visually, it reminds me of Developmental Math because of the extensive use of pictorial representations. Users posting online have compared the course to Singapore Math, but I don't really see much similarity. While they both emphasize conceptual learning and mental computation skills, Math Mammoth has a much more traditional feel. A distinguishing feature of this program is the authors amazing ability to simplify and clarify math processes so children can understand them easily. Even in printed form, this course is the easiest on the budget using a strictly by-grade comparison. And for those purchasing the complete program on CD (or download), the savings are even greater. Imagine getting a complete, masterfully taught math curriculum for grades 1-7 for less than \$150. I would call that frugal and smart.

Student Workbooks A and B for each level have varying numbers of chapters, each focusing on a math topic. These are sometimes very broad. For example, one very large chapter (68 pages!) in Worktext 4-B is simply titled, “Division”. It reviews division, and then covers every facet of fourth grade division. Since division skills are being built step-by-step throughout the chapter, there’s really no need for review or testing until the end; but it does make for a long teaching unit. Each chapter begins with a short introduction. This is where you will find any teacher instruction for the chapter, including background information, strategies and ideas for teaching lesson concepts, a summary of lessons by title (including number of pages for each), and a list of Helpful Internet Resources for further exploration, practice and enrichment. If the chapter is on a skill introduced in a previous grade, the skill is reviewed before the new material is introduced. Lessons each include a complete explanation of each skill being taught, numerous examples and models (many visual) to help students understand the concepts behind the math, and a reasonable number of problems for students to work to ensure comprehension.

The lessons vary from 1-5 pages each. For planning, the author suggests simply dividing the number of pages in each book by the teaching days rather than planning to teach a lesson a day. This would generally mean covering 1-2 pages a day depending on grade level. After the last lesson in each chapter there are one or two reviews. Chapter tests are contained in the separate Tests and Cumulative Reviews Book, as are cumulative reviews (taken upon completion of each worktext chapter) and a comprehensive test for the grade level. A nice feature is the inclusion of grading instructions and scales. If remediation is indicated, the author provides a website (www. homeschoolmath.net) for additional math worksheets by grade level and skill. Worksheets are randomly generated within your provided parameters, so each is different.

Use the Skills Review Workbooks books alongside the Math Mammoth curriculum to review concepts that are being taught. Each book is divided into chapters that correspond with the curriculum chapters. These workbooks are optional, and are intended for those who want a spiral review. Each review in the workbook is one page in length and includes a variety of math exercises. Students might write math equations, color pictures, or solve puzzles to put their math skills to the test. Some children require more practice than others, so use only the review pages you need. Skills Review Workbooks are printed with color for a little more visual appeal, and the number of reviews vary from book to book. Answer Keys are a separate book and are also printed in color.

As mentioned briefly before, I find the author’s teaching methods very solid, efficient, and effective. Her goal is to imbue the student with an understanding of the concepts in math rather than just how to solve problems and this is evident in her instruction. She consistently shares strategies, “tricks” and revealing insights into the mysteries of math, essentially putting a teacher right on the page. An example is in teaching beginners to add numbers with sums greater than 10. She tells students that when adding 9 to a number, the 9 “really wants to be a ten”, so you should take one from the other number to make it a ten, and then add the rest. I have seen few other curriculums (see Miquon Math) that teach students alternate, flexible ways like this to approach operations. Another feature I liked in the book was using gridded workspaces for solving problems. Especially for students just starting to use multiple-digit operations, it’s helpful to get them in the habit of keeping answers neatly aligned in columns. I also like the scale problems in Grade 4’s multiplication and other chapters. These are much like the ones in CTP’s Balance Math program and very effective for understanding how equations work. There’s also a healthy balance of word problems in the lessons with realistic, practical contexts. The geometry sections are particularly good, too, with ample hands-on work. The author even includes printable manipulatives for constructing your own geometric solids.

I got my nephew a set of Smartmax vehicles for his 4th birthday. His mother said he loves them, but wanted more! So I picked up this set for Christmas to add to his collection.

Our grand daughter loves helicopters and trains right now and this kit looks like it will give her some quality small motor skills that she needs at 6 years old. And I love the idea that she can construct so many different things on wheels. Many more hours of good play ahead.
