Math Mammoth Grade 1-B Worktext (International Version) is the student worktext for the second half of grade 1 mathematics studies.
In this part B, the main areas of study are:
* addition and subtraction facts within 10;
* clock to the half hour;
* geometric shapes and measuring length;
* adding and subtracting within 100; and
* counting coins.
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.
This international version differs from the Math Mammoth US version in these ways:
- It is all metric (no imperial measurement units are used);
- The currency in the money chapter is the Australian dollar;
- It uses British English spelling;
- Page (paper) size is A4.
The other parts of the Math Mammoth curriculum are: grade 1-A student worktext, grade 1 answer keys, and grade 1 tests and mixed revisions (all available on Lulu).
