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.
Sometimes children are given maths worksheets where they have to calculate the cost of things or work out how much change should be given on items that cost ūሴ when someone hands over a five dollar bill.You could do the following: o Get them to color in and name the three items _ o If there are no pictures on the worksheet then give them a sheet of paper to draw and color the items and then cut them out and paste them onto the worksheet _ o Once they have done this try to find five dollars in change and help them count out the money and calculate what is left
