Product Description
These are a range of activities/tasks to demonstrate mastery and develop deeper thinking and deeper understanding of year 3, Grade 2 and Grade 3 Addition and Subtraction objectives. For each objective there are at least 3 activities/tasks along with answers (where possible). The document is set up so that you can quickly jump to the objective you are covering and then simply print the appropriate pages. In addition, almost all the activities can be adapted to suit your class’s needs if necessary.
