Learning objectives

 * 1) Recognise a pattern in the set of data(in this class a set of coordinates)
 * 2) Recognise the variation(proportion/nonproportion)
 * 3) Recognise varying and constant terms
 * 4) Recognise dependency of one varible with the other
 * 5) Establishing the relationship between a variable and a constant
 * 6) Generalise the relationship and expressing symbolically
 * 7) Explore the possibility of having  different patterns
 * 8) Understand that every number pattern can be represented on the graph
 * 9) Joining the coordinates leads to a straight line or sometimes to non-Linear set
 * 10) Interprets the relationship between  the set of points on a straight line and on the non-linear set.
 * 11) Every pair of points when joined gives a straightline(infinite points can be located between two points
 * 12) Relation between the coordinates of set of points which makes a straightline is a Linear Equation /Otherwise Non-Linear

Notes for teachers

 * 1) Every Linear Equation represents a straightline .If the relationship(pattern)between two quantities can be represented as straightline then the relationship is in the form of linear equation
 * 2) A teacher can develop a lesson on Linear Equation with Geogebra application

 * Estimated Time
 * Materials/ Resources needed
 * Prerequisites/Instructions, if any
 * 1) Students have been introduced to graph(pictographs,bargraph,Histograms..)
 * 2) Students can make  the difference (Relationship)between axes and quadrants
 * 3) Refer to the Teaching Outline of Introduction to Coordinates
 * 4) Students are able to locate a given point on the graph if a set of coordinates are given
 * 5) Students are able to recognise coordinates of a given point on the graph
 * 6) Students can differentiate position of a point on the (NL)and also on the Quadrants
 * Multimedia resources
 * Website interactives/ links/ / Geogebra Applets
 * Process/ Developmental Questions
 * 1) Start with a Geogebra Drawing pad
 * 2) Give /ask students to give a set of coordinates
 * 3) You may get different patterns(assaign a group task)
 * 4) Ask the students to recognise coordinates of same  pattern
 * 5) Ask them to extend the pattern to say many more coordinates following the same pattern
 * 1) Ask the students visualise the points and visualise the pattern on the grap.
 * 2) Ask them to join the points (teacher can help student to join the points by using Straight line tool in Geogebra which is more meaningfull)
 * 3) This can be extended to say that Relation between the coordinates of set of points which gives/makes/results a straightline is a Linear Equation
 * 4) Continue with some more points with line joing the points and establishing the relation ship between variables also.
 * 5) Introduction to the degree of an equation may be discussed in subsequent lessons.


 * Evaluation
 * 1) Show them the graph of an equation and ask students to predict the pattern
