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 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 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.

Primary Math 2022 Edition (K-5) is a completely new revision retaining all the excellent teaching methods of the earlier Primary Math programs. Incorporating both cumulative assessments and challenging problem solving, mastery learning is emphasized. The scope and sequence is similar to previous editions and topics are aligned to state and national standards. ©2021-2022

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.

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

Hoping my kids will learn the why behind the method. To help concrete their understanding of math.
Jacqueline H on Jun 15, 2021
I have been able to just have my children follow along with the text up until this point but have decided to get the teachers guide for 5th if only to make checking his work less tedious! With 4 boys at our homeschool table, time is of the utmost importance! But these programs are so easy to follow along with and fun. I highly recommend them.
Nicole Jones on Mar 5, 2021
Good Curriculum. I have used Singapore Math from 1st through 4th grade.

Because we use this math in our homeschool lessons.
rachel d on Feb 25, 2019
We love singapore math because it has a lot of word problems and is great for kids with dyscalculia.
Talia S on Nov 6, 2018
Singapore Math is the best math program for us by far. It challenges the kids and works at an advanced level that meets state standards.
Perplexed on Aug 2, 2018
We've used this program from the beginning and find it to be thorough and engaging.
Stefanie B on Apr 30, 2018
We have been using singapore math since 1A. We really like it. I got this set to have on hand when we finish 4B so I can use it during planning. I do 5-6weeks of school and then take 1 week off to plan. This planning week helps me plan for chunks at a time. We have year goals and then planning weeks throughout. This gives me flexibility to change or adjust if something changes through the year.
Emily D on Apr 4, 2018
Singapore Math helps my children think more fully about numbers instead of just following algorithms. We once tried a different curriculum and soon came back to Singapore. We do not often need the manipulative exercises in the teacher's book, but we like to have them, then the visual examples, and then just the numbers to cover each topic. Great curriculum and 2/3rds of the books are non consumable to use with future children.
Katie N on Mar 11, 2018
We have used Singapore through 4th grade and it's gone well so we'll continue on!
Bethany G on Feb 24, 2018
I've been extremely happy with Singapore's math curriculum and wanted to continue using it for the next grade.
Alyssa T on Nov 29, 2017
Been using the Singapore Primary Mathematics Series for both my boys with great success since second grade.

Excellent program!
Maria Rosario Z on May 23, 2017
Excellent math textbook and workbook
Veronica B on May 5, 2017
I am looking for a new math option for my daughter.
Amy W on Jan 12, 2017
So, so happy with my children's math skills from using Singapore!
Betsy N on Aug 3, 2016
My daughter who dreads paper & pencil work has used Singapore Math since 1st grade and LOVED it! SM is great for kids who love mental math. However, level 5 was frustrating for us. While I appreciate that Singapore wants students to understand how to solve for an unknown by thinking it out vs. using a algebraic formula, there are SO many story problems that require this that I really wished that they would have added in the algebra formulas at some point to save time (and mom's brain strain).
Kimberly D on Jul 31, 2016
I like being able to buy all the books I need in one item so I don't have to search for everything and I know I have all that I need.
User on Jul 26, 2016
Singapore seems to be really ahead grade-wise in Math. Singapore is the Math my son prefers, as he excels in this area!
User on Jul 7, 2016
Singapore is solid, straight forward and requires good mathmatical logic and application. It is also strait forward for the teacher/parent. I do like the teacher's guide for mental math pages (quick review/quiz) and for additional help when more assistance is needed to drive home the concepts.
April J on Feb 25, 2016
To continue my son's singapore math curriculum.
Karen G on Jan 22, 2016
Encourages mathematical thinking not just rote memorization.
Rebekah R on Nov 14, 2015
I think this is a great program that is working well for my daughters.

My favorite elementary math curriculum
After extensively researching curriculum for my rising 5th grader, this one was the most challenging, and the one closest to the education he was getting as a gifted student at his previous school. One thing both of us really liked is that the worksheets give plenty of space for children with large handwriting (my son asked me to add that in the review!)
