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

I love the Concrete --> Pictorial --> Abstract approach Singapore Math uses; it really helps kids make sense of the mathematics!
Sarah E on Dec 20, 2020
I have used this program with my older child and am even more excited to use it with my youngest due to its heavy emphasis on concrete learning when introducing a new concept. The approach that Singapore utilizes, concrete-pictorial-abstract, has allowed my eldest to easily learn difficult math concepts that then make sense when asked to compute problems mentally or to solve abstract problems.
Rhea C on Nov 17, 2020
Extra math practice for my kids.
Sridhar G on Nov 17, 2020
We have started the Primary Mathematics 1A and found that my kids each wanted their own workbook so this one is an add on. So far the program is great and the kids have engaged with it and seem to enjoy it.
Jessica G on Aug 30, 2020
I have worked with Singapore Math in the past. My children enjoy the colorful pictures and it is easy for them to follow the math concepts that are taught. Sometimes they will even get the textbooks out on their own to read independently.

Melanie D on May 22, 2019
I've liked Math Mammoth for how straightforward it is, and I've heard this is similar and an excellent curriculum. I'm buying this to try with a younger child to alleviate competition between brothers, should the younger catch up to his older brother in the content.
Kristine R on Apr 24, 2019
I have tried so many math curricula for my son on the Autism Spectrum. I think this one with the bright colors and the way they break down concepts may work for him.

We are really enjoying our first year with Singapore Math. The teacher manual, textbook and workbook are a good system - giving variation in how the child interacts with the material. The examples are clear and the workbook images are engaging. Overall very happy.

This is great so far! I homeschool my 1st grader and we're loving it. It starts out a little bit easy for him, but that's a good thing since we need the review after the summer. I highly recommend this math program!

an appealing approach to first math
This go-through will be my second time in this workbook, with my second son. The Singapore approach to math is refreshing and uncluttered--concrete to pictorial to abstract overall, with the workbook used for the latter two stages. The pictures are very endearing and age-appropriate, and for what could be very repetitive activities at this level there are instead a variety of attractive exercises that my kids have loved. It's nice to be able to take things at our own pace, too--we can practice more on our own if needed. To accompany the workbook, I purchased the textbook years ago (for the first son), and I've also benefitted from the home instructor's guide (especially for first getting to understand the Singapore approach to lessons--for the textbook and workbook are pretty sparse on instructions and goals!).

Very Good
We are using this with our son. It is challenging, but thorough and effective. He really understands math and mental math at that! I think we will be using this for the long haul.

Not only have I been impressed by how quickly my son has picked up math using Singapore but my extended family is amazed He has enjoyed doing the mental exercises in his head and loves solving problems given by his grandparents Singapore Math uses a natural progression toward learning new concepts The sequencing has been easy to understand and follow I wish this math program had been around when I was in school It has me hooked! The cost is minimal and the preparation is easy It's wonderful for kids who dislike writing every step out on paper Singapore math is my son's favorite subject

I have used both Saxon and Singapore for first grade math and much prefer Singapore although we will continue doing some parts of Saxon However we did find the Singapore textbook and workbook need to be supplemented with extra problems about halfway through (when students are starting to do addition with numbers up to 20) The Extra Practice problems are good; there are just not enough of them That's why I ordered the intensive practice books also I would not recommend the Challenging Word Problems books which I feel are misnamed - at least at the 1 level They are wordy but not challenging For the most part the student need not read the problem If he sees a 7 and a 2 in the section on addition he knows the answer is 9 and in the subtraction section 5 without reading the problem In other words they aren't really word problems just arithmetic drills with references to kids' names and papayas tops and other countable objects

After completing Saxon Math with my daughter for first grade and wanting a change I bought Miquon and Singapore Primary Mathematics (Singapore version) The Singapore version did not bother me since I am Asian myself My daughter LOVES Singapore Math and I do too! She does not like too many problems on one page nor too much repetition of the same thing so Singapore Math works well for her
