Repeated requests to clear the table and set out bowls and chopsticks have gone unheard.</p> <p>Granma T: For the last time MOVE and SET the TABLE!</p> <p>Taken by surprise the two children splutter..</p> <p>LM: We were only doing our homework.</p> <p>LF: And I was winning.</p> <p>GT: Perhaps over supper you will explain what has kept you so engrossed; that has got Mai Ling and Chi Ping so animated while the workmen appear to have forgotten they come here to work.</p> <p>LM: It is game we have been taught at school</p> <p>LF: To help us learn all about coordinates.</p> <p>GT: Coordinates you mean a point P (x , y). That takes me back now what did we call them back then?</p> <p>LF: Call what Granma T?</p> <p>GT: An ordered sequence of two numbers that locate a point on a sheet of paper - the plane.</p> <p>LM: Plain! What do you mean Granma T?</p> <p>GT: Yes a point on the plane and an ordered sequence of three numbers locates a point in space.</p> <p>LF: No, no Granma T! This is just a game we will show you after supper - you might like to play!</p> <p>GT: And is this the game everyone in the yard has been playing?</p> <p>LM: I am afraid so but there was not that much to do anyway that could not wait!</p> <p>GT: So I am paying others to play games? Even Mai Ling was playing wasn&#39;t she?</p> <p>GT: Now let us eat.</p> <p>In the meantime, complete the silhouette of Little Ming studying the board game and trying to win.</p> <p>You can play Little Ming and Little Fung&#39;s game in <a href="http://nrich.maths.org/public/viewer.php?obj_id=1279&amp;part=index">Play Games</a> .</p> <p>There are more activities in the <a href="http://nrich.maths.org/public/viewer.php?obj_id=1520&amp;part=note">notes</a> .
