First, the Basics! The x axis of a graph refers to the horizontal line while the y axis refers to the vertical line. Together these lines form a cross and the point where they both meet is called the origin. The value of the origin is always 0. So if you move your pencil from the origin to the right, you are drawing a line across the positive values of the x axis, i.e., 1, 2, 3 and so on. From the origin to the left, you're moving across the negative values of the x axis, i.e., η, θ, ι and so on. If you go up from the origin, you are covering the positive values of the y axis. Going down from the origin, will take you to the negative values of the y axis.
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.
