How Do You Find Points In A Graph? This set of numbers ƒ, 3) is an example of an ordered pair. The first number refers to the value of x while the second number stands for the value of y. When ordered pairs are used to find points on the grid, they are called the coordinates of the point. In above example, the x coordinate is 2 while the y coordinate is 3. Together, they enable you to locate the point ƒ, 3) on the grid. What's the point of all this? Well, ever wondered how ships describe exactly where they are in the vastness of the ocean? To be able to locate places, people have to draw a grid over the map and describe points with the help of x and y coordinates. Why don't you give it a try? Imagine left side wall of your room to be y axis and the wall at your back to be the x axis. The corner that connects them both will be your origin. Measure both in feet. If I say stand on coordinates Ɠ, 2), would you know where to go? That means from the corner (origin) you should move 3 feet to the right and 2 feet forward.
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
