Provide useful math worksheets: Several free math worksheets are available online. Parents can download and provide these to their children as working on these worksheets surely improves their skills. Parents can also encourage them to practice these worksheets repeatedly. It is one of the convenient ways to brush up your knowledge on a particular topic.
Another problem with almost all worksheets is that they don't prevent incorrect answers. Self_checking worksheets just let the student know they did something wrong__after the fact. I am a firm believer in the concept that, if at all possible, learning should be structured in small chunks in such a way that there is very little possibility for error. Worksheets often allow for mistakes to be made and then to be repeated many times. A mistake that gets practiced is extremely difficult to correct. This especially happens when worksheets are used as time fillers or baby sitters and the work isn't really being supervised.
