Math Mammoth Grade 1-A Worktext (International Version) is the student worktext for the first half of grade 1 mathematics studies. In this part A, the main areas of study are:
* The concepts of addition and subtraction;
* strategies for addition and subtraction facts; and
* developing understanding of whole number relationships and place value till
The worktext is in full color, and contains both the necessary instruction and the problems & exercises (the 'text' and the 'work'), and is for the most part self-teaching. It does not contain the answers.
The other parts of the Math Mammoth curriculum are: grade 1-B student worktext, grade 1 answer keys, and grade 1 tests and mixed revisions (all available on Lulu).
