Those children who practice sufficiently mental arithmetic have the advantage of learning more advanced math easily. This workbook presents those exercises in a way that children would progress gradually to more advanced level without difficulties. The first few pages are addition and subtraction from 1 up to 3. Then more ranges of numbers (up to 12) and different ways to present the problems are adding to the exercises.
