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.
In this modern, technology lead world it is easy to overlook the importance of basic mathematics and mental arithmetic. When every mobile phone has a calculator built in, and every website automatically adds up your shopping cart, who needs to add up in their head? The fact is that mathematics is a vital life skill and as adults we know it is something we use every day in our adult lives. We know that it is essential that we teach our children how to do maths from a young age, but sometimes it is easy to overlook the simple steps we can take at home. We can all remember learning our times_tables at school _ one times one is one, two times two is four, and so on _ but there was a reason why we learnt this way, because it works. But it's not just about learning the times tables in sequence through repetition, it's important to get kids practicing with varying levels of multiplication problem. Working through problems and then checking the answers afterwards is a simple way to practice multiplying numbers.
