This math workbook from the Dr. Pi Squared Math Workbooks series focuses on multi-digit addition. There is ample workspace for students to write large answers and still fit their solutions comfortably into the space provided. The problems appear in a large font size, since students usually write larger than standard textbook fonts. High-quality, durable, bright paper is used (instead of standard workbook paper, which often tears easily and appears dull in color). Each section begins with a large, fully-solved example to illustrate the technique and to serve as a useful guide. Answers are nicely organized by page number in the back of the book to allow students, parents, or teachers to quickly check the answers. An aesthetic, full-color addition table is conveniently located on the back cover for easy reference.
