TouchMath recognizes that some students may require additional practice to achieve addition 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 at home. Students will engage in activities focused on subtraction instructional strategies such as reviewing addition fact 0-9, continuance counting, mastering two, three, and four column addition and exploring addition with regrouping. With the inclusion of an answer key, you can easily monitor student progress and guide your instruction accordingly.
