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.
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!
