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.
Books _ Among the dozen or so math word_problem books of note published in the past decade, one, written by Mary Jane Sterling, from a well_known, popular brand of information books, which I'm unable to name here, stands out. The publisher has put a decent chunk of the book online at books.Google.com (go to books.google.com and search for sterling word problems). Striking Difference in Child Development _ If you are considering arranging extra math drills for your child, keep in mind that story problems are more like the real_life problems he or she will encounter, and, they help develop his or her critical_thinking skills. Children develop mental maturity like they do physical maturity. Think about the strikingly different mental development that ordinary math worksheets might foster in comparison to math word problems. Priorities _ Ordinary math worksheets certainly serve a purpose, but think carefully about the ratio of those to story problems when helping your child prioritize his or her available math study time.
