Line 57: − #'''Familiarising to Cartesian Coordinate system - Activity No 1''' [[http://www.mathopenref.com This source taken from mathopenref.com]] − To introduce the idea, consider the grid on the right. The columns of the grid are lettered A,B,C etc. The rows are numbered 1,2,3 etc from the top. We can see that the X is in box D3; that is, column D, row 3. − D and 3 are called the coordinates of the box. It has two parts: the row and the column. There are many boxes in each row and many boxes in each column. But by having both we can find one single box, where the row and column intersect.<br> − [[File:table.gif|200px]]<br> − '''The above activity can also be done in a class room by asking to find coordinates of each student's position'''<br> − − # '''Idea of introducing to coordinates - Activity No2''' − [[http://tube.geogebra.org/material/show/id/147058 Play with the geogebra applet to familiarise with coordinates]]
