NumberSense Workbook 20
The NumberSense Workbooks have been developed to provide independent written activities for children. The workbooks can be used by teachers working with small groups of children at a time, to keep the other children productively engaged, as well as in whole class settings. Three to four workbooks per year, a page a day. In the Intermediate Phase the children complete pages in the workbooks in preparation for the focus group sessions with the teacher.
