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.
Which brings us to the purpose behind this article. One of the most effective ways I've found to help kids in a focused area of weakness are printable math worksheets. The big problem with concept_based instruction is lack of practice. Printable math worksheets solve this problem nicely. As a teacher, I supplement my lessons with appropriate worksheets. I can then check a student's progress. I can also monitor how much work they actually are doing. For parents, printable math worksheets are a great tool for drilling their own kids in those same skills. Make no mistake, printable math worksheets are not a relic from the past that needs to stay buried. They are useful, focused tools for the classroom or at home. You can find resources all over the web for worksheets. Finding answers for worksheets, however, is not that easy. For that you often have to use paid subscription services.
