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.
Graphing Linear Equations. If you have several sets of x and y coordinates, you can now draw lines on a graph. Free math worksheets can drill you on plotting x and y coordinates while graphing linear equation. A linear equation when drawn on a line graph always yields a straight line. Take "y = 2x + 1" for example _ a linear equation. Assign any three numbers to x, and then solve for y. Whatever numbers you assign to x and whatever y comes out to be, you will end up with a straight line. Remember to practice on easier math worksheets first before moving on to writing a linear equation or to the systems of linear equations. Good luck!
