At the end of all levels, children are greeted by a celebration and encouraged by a computer voice to change topics.
For example, some programs use incentive tools similar to those found in video games. Each time a child completes a satisfactory score on a worksheet, the program congratulates them and gives them a score. With each level, the score increases. After a certain number of points, the student reaches a named level, such as captain or commodore.
As children become more confident in their math skills, give them worksheets one grade level above their current grade. Help them if necessary, but when students become successful in the upper level workbooks; their confidence will really improve. The seed will be planted early and parents can watch as it grows.
Another strategy involves allowing your child to spend some time on a computer playing math games. The computer can be a wonderful resource that supports math and other subject area skills. Software is available that will measure a child's math skill level.
