Multiplication worksheets are a quick and easy way to introduce some math revision at home. At first your kids may not appreciate being given extra "homework", but the advantages they will gain from "sharpening the saw" and practicing their math will serve them well; both back in the classroom and on in to later life. With a basic knowledge of Microsoft Excel or Word you can easily make your own math worksheets, but not everyone has that knowledge so it's fortunate that there are many websites dedicated to providing free printable resources, usually in PDF format. You just download, and print _ the only software required is the free Adobe PDF reader.
Who's Fault? _ Is it his fault that he lacks confidence with word problems? Not entirely. Our actions, as educators, seem to imply a belief that solving word problems should come more naturally than simpler operations like arithmetic and algebra. Many parents and teachers feel justified in encouraging (i.e. forcing) a child to work hundreds or thousands of math worksheets, drill multiplication tables, long division... but few encourage solving hundreds of story problems. One suspects that the relative ease of creating and checking ordinary math worksheets keeps the focus of math education on simple, atomic operations at the expense of more holistic story problems.
