Number Sense Workbook Grade 1 (1) - The Number Sense Workbook Series has been developed to provide independent written activities for children. The series 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. The workbooks allow for differentiated support with different children in a class working in different workbooks and hence on different activities that are well matched to their developmental state. The series can also be used by parents wanting to provide daily support to their children. The richly illustrated pages are engaging, challenging and developmental in nature.
