Primary Math Standards Edition was adapted to meet the pre-Common Core California math standards. If you compare the Primary Math US Edition and Standards Edition, some topics have been rearranged, and the Standards Editions has additional content covering 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. Each grade consists of two semester sets to be completed in one year, the A textbook and workbook for first semester and B textbook and workbook for second semester.
The Teacher’s Guide provides instruction, as well as daily lesson plans, assignments, answers to the textbook and workbook assignments, lists of suggested manipulatives, and reproducibles. Although written for classroom use, they are fairly easy to use one-on-one. Teacher’s Guides also include a 6-month subscription to Math Buddies, an online program created by the publisher for practice and reinforcement. Please note that we currently do not stock the Home Instructor Guides.
Sets include a textbook, workbook, and teacher guide. If you don’t need all of the information in the Teacher Guide, multi-grade Answer Keys are available separately. Optional supplements for each grade include the Test Books (A and B), and the Extra Practice Books (one book covers both A and B at grade level).
