Primary Math - Standards Edition (Gr. 1-6)
No material from the Primary Math US edition was removed for the Standards Edition (SE), only rearranged between levels. A few units have been added primarily in probability and data analysis, negative numbers and coordinate graphing. A glossary of terms was added to each of the textbooks. In levels 2A through 5B there is now a cumulative review after most units in both the textbook and the workbook. 6A and 6B feature reviews after every other unit. Many of the units have a few pages that have been added in order to "reteach" a concept from an earlier level. There is some material that had been removed from the 2nd edition that has been added back in - some of the reteaching pages, additional pages on fractions and mental math learning tasks, along with some problems added to the reviews. Levels 3A through 6B are now in color.
As in the 3rd ed., you need both the textbook and the workbook. The textbook contains the learning tasks along with the practices and reviews that are to be done in class. The workbook contains the independent work. Materials are now also available for 6A and 6B. Please note that the US ed. Teacher's Guides and Home Instructor's Guides and Answer Key Booklets cannot be used interchangeably with the Standards Edition material.
Both the Teachers 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 Teacher Guides are more oriented to the classroom while the Home Instructor Guides are more geared to working one-on-one with a student. However, both provide detailed lesson plans. The Teacher Guides have daily lesson plans while the Home Instructor Guides provide teaching segments indicating the number of weeks to spend per unit. A significant difference between the two is that the Home Instructor Guides have a sidebar column that shows assignments complete with answers. Assignments in the Teacher Guides are listed within the lesson plans and all answers are in the back of the book. Both include lists of suggested manipulatives and materials and included in the appendix of each are mental math worksheets and some teaching helps. (please see our Singapore Math Manipulative category at the end of the Singapore Math section.)
Extra Practice books provide additional problems for A and B books at each level.
NOTE: The Math 6 Teacher Guides have some incorrect answers. An errata sheet is available at SingaporeMath.com, showing the correct answers. Given the limited amount of explanatory information in the Teacher Guides compared to the Student Books, you may consider not purchasing these guides. ~ Janice
