Category Description for Primary Math U.S. Edition (Gr. 1-6):

I'll admit, my initial reaction to this program was skeptical. The textbooks are thin and have a straightforward, no-nonsense appearance. Texts switch from full-color to two-toned pages after second grade, and all workbooks are printed in black and white. After spending a great deal of time evaluating the program's contents, however, my opinion has improved considerably. Primary Math uses a concrete-to-pictorial-to-abstract approach to teaching. Concrete illustrations are incorporated heavily in the early grades, gradually giving way to more abstract representations so that math is learned meaningfully. The program builds strong problem solving, critical thinking, and computational skills through well-chosen practice problems.

Each grade consists of two semester sets to be completed in one year. For example, the complete first grade curriculum requires the 1A and 1B textbooks (non-consumable) and the 1A and 1B workbooks (consumable). Workbook assignments are directly correlated with each textbook. Small arrows, usually located in the lower left hand corner of a page, specify when to pause in the text and what exercise number to complete.

Brief teacher’s instructions are provided in each textbook’s preface, which I highly suggest reading. Although the pace of the course really depends on the individual student, 2-3 pages in the text is usually enough for one day’s lesson. To effectively use the textbook, the teacher should study the examples ahead of time in order to determine the best way to verbally explain a concept to the student. Teacher-student or student-student discussions are an important part of this program. Unfortunately, the text doesn’t tell you how to facilitate discussions. Fortunately, there are now Teacher Guides and Home Instructor Guides available for all levels.

Both the Teacher Guides and the Home Instructor Guides include answers to the textbook and workbook problems. Both of these publications help teachers understand the course material and provide suggestions to help you introduce concepts. As a general rule, the TGs are more oriented to the classroom while the HIGs are more geared to working one-on-one with a student. However, both provide detailed lesson plans. The TGs have daily lesson plans while the HIGs provide teaching segments indicating the number of weeks to spend per unit. A significant difference between the two is that the HIGs have a sidebar column that shows assignments complete with answers and often solutions. Assignments in the TGs are listed within the lesson plans and all answers are in the back of the book. Also included in the appendix of each are mental math worksheets and some teaching helps. Answers (but no solutions) to the U.S. edition textbooks and workbooks are also available in separate answer key booklets. For convenience, we have put together sets for each grade and semester that include the text, workbook and HIG.

TGs and HIGs both include lists of suggested manipulatives and materials. (please see our Singapore Math Manipulative category at the end of the Singapore Math section.

Extra practice sets are included in all textbooks, except first grade. These problem sets are optional and should be done only after the workbook exercises for that section have been completed. Cumulative review sections are also incorporated into the text, although not on a daily basis like Saxon. Review sections are also included in each workbook. Although these problem sets are optional, I would strongly suggest completing the extra practice. Some of the review sets are quite lengthy, and you might want to consider devoting a day’s lesson to review whenever a longer set arises. I suspect a key factor to this program’s success in Singapore is that students are both motivated and expected to practice their math skills through homework and optional problem sets use is strictly up to the teacher, although Primary Math tends to emphasize mental calculations.

While some believe that Primary Math contains “just the right amount of practice”, others believe not enough is provided. For students who feel they need more practice to really “own” a concept or skill, a variety of supplements, specifically designed to complement Primary Math, are available.

Compared to Saxon Math, Primary Math encompasses a narrower scope. While Saxon Math covers coordinate graphing, negative numbers, square roots, and probability, these topics are omitted from Primary Math and are not covered until New Elementary Math. The smaller scope, however, allows the program to emphasize the basics. Primary Math focuses on the four arithmetic operations (using whole numbers, fractions, and decimals), perimeter, area, volume, angles, quadrilaterals, symmetry, time, length, weight, money, graphs, and algebraic expressions (introduced in 6th grade). Saxon Mathmoves a bit slower introducing Algebra in Math 87. Miquon, which only covers grades 1-3, correlates very well with Primary Math.

Category Description for Primary Math (K-6):

Primary Math US (1-6) is an adaptation of the 3rd edition for use in the U.S. Although a small amount of content (division of fractions) from the 2nd edition was added back into the US edition, it is almost identical to the 3rd edition. The US edition adds sections for U.S. customary measurements and uses U.S. spelling and conventions. We expect this edition to be available indefinitely. 2003 copyright dates.

Category Description for Singapore Math Programs:

Countries around the world first became interested in Singapore’s math curriculum when results of the Third International Math and Science Study (TIMSS) were published in 1995. Conducted by the International Study Center at Boston College, achievement tests in both math and science were administered to students in over 40 countries. Students from Singapore ranked highly in mathematics achievement: 1st in the fourth, seventh, and eighth grade levels and 2nd at the third grade level. Results for the U.S. were disappointing: 10th in the third grade, 11th in the fourth grade, 23rd in the seventh grade, and 27th at the eighth grade level. In a follow-up study in 1999, Singapore again ranked 1st in eighth grade math achievement while U.S. eighth graders ranked 19th. Although a first place ranking does not necessarily imply the best program, something about Singapore’s math program was working.

“Singapore Approach Math” is a general term referring to a type of mathematical instruction (i.e. curriculum) developed from a syllabus designed by Singapore’s Ministry of Education in the 1980s. There were a number of revisions and the 3rd edition was the last edition used in Singapore. The good test scores were associated with this material and all of our Singapore Approach Math programs are based primarily on the 3rd edition although it is no longer available for sale. Components from different editions are not interchangeable but a student can move between the editions in-between levels.

Primary Math US (1-6) is an adaptation of the 3rd edition for use in the U.S. Although a small amount of content (division of fractions) from the 2nd edition was added back into the US edition, it is almost identical to the 3rd edition. The US edition adds sections for U.S. customary measurements and uses U.S. spelling and conventions. We expect this edition to be available indefinitely. ©2003

Primary Math S/E (Standards Edition) (K-6) was adapted to meet the pre-Common Core CA math standards. An additional amount of content (probability, data analysis, negative numbers, coordinate graphing) from the 2nd edition was added back in and topics were rearranged but it is similar to the US edition. Cumulative Reviews at the end of each Unit and practice sets within each unit were added. Textbooks are in color. ©2008 This edition will be phased out. Includes Earlybird Kindergarten Math.

Primary Math CC (Common Core) (K-5) is aligned to the Common Core State Standards and is another adaptation of the 3rd edition. Only minor changes were made to the scope and sequence. Unit Reviews are no longer cumulative and Practices were removed although some of the content was incorporated into the lessons. ©2014 Includes Earlybird Kindergarten Math CC. This edition will be available for the foreseeable future.

New Elementary Math (7-8) is a no-frills program based on an older Singaporian program and covering integrated algebra and geometry.It’s considered a sequel to the Primary Math programs.

Dimensions Math (7-8) is an updated and more colorful version that is now aligned to the CCSS. It’s also considered a sequel to the Primary Math programs.

Math in Focus (K-8) was developed by Great Source (a division of Houghton Mifflin Harcourt) in conjunction with Marshall Cavendish (the original publisher in Singapore). Although the basic instructional sequences are similar and the content is very close to the SE, material added to the most recent editions brings it into alignment with CC. Math in Focus has a more American look and “feel.” ©2010, 2014

Robin H on Oct 1, 2018
I read online that Singapore Math is similar to Math Mammoth that we have been using, but has less on a page and less problems, so if the student picks math up pretty quickly, it can be a better fit. So, we are trying this out this year :)
Shannon W on Aug 22, 2018
Having read so many reviews I settled on this curriculum to pick up after RightStart Math C ... we needed a little more practice and a little less of me talking and directing the learning ;0) My boys were ready for a change. We've coupled it with Beast Academy for variety.

Used this program for last 2 years and daughter responds well to approach. Also very well regarded curriculum.
Beverly S on Nov 27, 2017
I need it for homeschooling.
SHANA S on Nov 2, 2017
Enjoyed using this curriculum for the past 2 years
Amy P on Sep 26, 2017
I purchased Singapore Math by Thinking Kids to use as our homeschool 3rd grade math curriculum. When it arrived I didn't like that there was little to no references or examples on how to solve problems. When I read the back cover it states its a "perfect supplement to classroom work" workbook. This one comes with a text book and a student workbook, plus it comes with a teachers guide. I'm really looking forward to using Singapore Math curriculum and this one looks like a complete program.
Nimsay M on Aug 30, 2017
We've used Singapore book 1 and 2
Larissa A on Aug 20, 2017
We have used Primary Math for the past 2 years and I have been very pleased with my kids' mental math and overall math skills. The Homeschool Instructor's Guide is very helpful for those of us who were not taught math in this way. My own math skills have improved along with my children's.

I have enjoyed supplementing my daughter's public school education with Singapore Math.
Heather H on Jun 29, 2017
My son has been using Singapore Math for a couple of years. He loves the bright and fun graphics in the work texts. Their method makes the visual learner thrive! My son can do mental math in a snap now.
Ellen S on Jun 15, 2017
We have used Primary Mathematics 1 and 2 in our homeschool and are pleased with the methods taught for number decomposition and mental math. We'll keep on using Primary Mathematics.
AMANDA M on Jun 7, 2017
We homeschool our children and Singapore math has been the best program we have used yet. We have tried others but nothing compares to Singapore.

I like the way it trains children to see numbers from different angles and to master math facts.
Stephanie S on Oct 6, 2016
I like the mental math approach
Jessica P on Sep 12, 2016
We have used Singapore for K, 1st, and 2nd, and a pleased to continue to use it for 3rd grade.
Tiffany S on Aug 12, 2016
My son has done very well with the Singapore style of math, and I believe it has helped him better understand number relationships and how to do mental math faster. It is very different from what I was taught in school, but it works great for my son and I have heard that learning this style will help him better understand the harder math concepts later on. It very much depends on what works best for each individual child, but personally we have had success with Singapore.
Rebecca R on Aug 7, 2016

Good program
My daughter does well with Singapore math. She has done this program since 1A and is good in math. The teacher's guide is important to me as it shows me how to teach her. Plan on using this program throughout the elementary years.
