Math Skills (Harcourt Family Learning)
If a math mastery supplement is what you are looking for, consider this series for a moment. Covering all of the skills appropriate to the first six grades, students will be strengthening their math skills and problem-solving methods right from the very first page. The workbooks are clean and clear with color throughout - making them very attractive, especially to children who already enjoy the workbook style. All pages are perforated and consumable (though not reproducible) and an answer key is included in the back of each book. Workbooks are 128 pages long and are an exceptional value when the price is compared to many other workbook series.
