There are three editions to Primary Mathematics to serve the diverse needs of the students and schools in the United States. It is pretty popular with homeschoolers since it was the first Singapore Math curriculum available for the U.S. market. In this post, we review the Primary Mathematics U.S. Edition that was adapted to the U.S. market by Singapore Math, Inc.

There are 3 editions to Primary Mathematics – the U.S Edition, the Standards Edition, and the Common Core Edition. In this post, we will review **Primary Mathematics U.S. Edition** since this has been the more commonly used version among US homeschoolers.

#### Primary Mathematics U.S. Edition (Grades 1 – 6)

Primary Mathematics U.S. edition was modeled after the original program used in Singapore years ago in the 1980s, but with U.S. measurements and currency. It is no longer used in Singapore.

#### Standards Edition (Grades 1 – 6)

The Primary Mathematics Standards edition was written to meet the 2006 Mathematics Contents Standards for California Public School issued prior to the Common Core State Standards.

#### Common Core Edition (Grades 1 – 5)

The Primary Mathematics Common Core edition was written to align with Common Core State Standards.

## Primary Mathematics U.S. Edition

The Primary Mathematics offers material from Grades 1 to 6.

- Primary Mathematics U.S. Edition Textbooks (A & B)
- Primary Mathematics U.S. Edition Workbooks (A & B)
- Primary Mathematics U.S. Edition Teacher’s Guides (A & B)
- Primary Mathematics U.S. Edition Home Instructor Guides (A & B)
- Primary Mathematics U.S. Edition Extra Practice
- Primary Mathematics Intensive Practice (A & B)

### Primary Mathematics Cost

The cost of implementation is pretty reasonable. The cost of each textbook is about $15. The cost of each workbook is about $15. You will need 2 textbooks and 2 workbooks for an academic year (A & B). The Home Instructor’s Guide costs about $20 and a Teacher’s Guide costs about $25. You can choose either the Home Instructor’s Guide or the Teacher’s Guide. You’ll need 2 of either guide (A & B) for the academic year. Extra Practice costs about $14 and you only need 1 for the academic year. You can also find second-hand books on Amazon.com or AbeBooks.com or eBay

### Primary Mathematics Textbook

This textbook is in dual-color (black and blue) as you can see in the thumbnails. The book is softcover. The layout is simple.

### Primary Mathematics Workbook

The Primary Mathematics Workbooks are in black and white and there are 2 workbooks for each academic year. For example, in 4th Grade, there is a 4A and 4B workbook. The layout is pretty simple and a student would write in the workbooks. The workbooks are softcover and pretty lightweight so you can easily bring it on a road trip or to grandma’s house. The contents page lists down the main topic and then the exercise number. The contents page does not list down the subtopic of what the exercise corresponds to but one can refer to the actual content to see what it is.

### Primary Mathematics Teacher’s Guide

Homeschooling families use either the Teacher’s Guide or the Home instructor’s Guide. Some just use the textbook and workbooks. The teacher’s guide is spiral-bound, softcover. The Teacher’s Guide is broken down into ‘Units’ and under each ‘Unit’, there are ‘Parts’. The Teacher’s Guide also contains the answer key to the textbook and workbook.

Each Unit in the Primary Mathematics Teacher’s Guide lists the objectives and makes reference to the textbook pages, workbook pages, and activities that correspond to each ‘Part’ in the ‘Unit’. It also states the number of recommended sessions to teach each ‘Part’.

Each ‘Part’ goes into more detail the objectives, materials needed, homework, and activities for that particular sub-topic.

### Primary Mathematics Home Instructor’s Guide

The Home Instructor’s Guide is softcover. The Home Instructor’s Guide is broken down into ‘Units’ and under each ‘Unit’, there are ‘Parts’. The Home Instructor’s Guide also contains the answer key to the textbook and workbook.

The Home Instructor’s Guide contains a weekly schedule which can be helpful for homeschooling parents to plan their lessons. It lists the lesson and the corresponding pages to the textbook and workbooks.

Each ‘Part’ contains objectives, notes, suggested activities, corresponding textbook pages, and homework assignments. There is an instruction page to indicate what the symbols refer to.

### Primary Mathematics/ Singapore Math Intensive Practice

The Primary Mathematics/ Singapore Math Intensive Practice book can be used for more practice. The book contains more practice questions for each topic.

### Primary Mathematics Extra Practice

As the name of the book suggests, the Primary Mathematics book contains extra practice questions.
