TouchMath recognizes that some students may require additional practice to achieve subtraction mastery. These workbooks contains 56 student activity sheets. The activity sheets themselves are scaffolded with visual cues, ensuring that students receive the guidance they need to succeed. Students will engage in activities focused on subtraction instructional strategies such as subtracting two numbers, subtracting two and three columns with and without regrouping and understanding place value. With the inclusion of an answer key, you can easily monitor student progress and guide your instruction accordingly.
