Concept #1 Data Patterns

 * 1) Recognise a pattern in the set of data(in this class a set of coordinates)
 * 2) Recognise the variation(proportion/nonproportion)
 * 3) Explore the possibility of having  different patterns
 * 4) Understand that every number pattern can be represented on the graph

Learning objectives

 * 1) Establish/Guess the relationship between the set of coordinates
 * 2) Recognise varying and constant terms
 * 3) Recognise dependency of one varible with the other
 * 4) Establishing the relationship between a variable and a constant
 * 5) Generalise the relationship and expressing symbolically

Learning objectives

 * 1) Analyzing a linear equation

Notes for teachers
Note for the Teachers Analysing a Linear Equation Class Interaction(with activity)
 * 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

Activity No #1 Analyzing a Linear Equation
Computer(Geogebra),projector,Blackboard (Lesson can be developed using graph sheets also) Refer to the Teaching Outline of Introduction to Coordinates 1. Start with a Geogebra Drawing pad 2. Give /ask students to give a set of coordinates You may get different patterns(assaign a group task) 3. ask the students to recognise coordinates of same  pattern 4. ask them to extend the pattern to say many more coordinates following the same pattern (NOTE:Students may recognise same pattern or some may not recognise the pattern. ) 5. Ask the students visualise the points and visualise the pattern on the grap. 6. 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) 7. 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 8. Continue with some more points with line joing the points and establishing the relation ship between variables also. 9. Introduction to the degree of an equation may be discussed in subsequent lessons.
 * 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
 * 1) Students are able to locate a given point on the graph if a set of coordinates are given
 * 2) Students are able to recognise coordinates of a given point on the graph
 * 3) Students can differentiate position of a point on the (NL)and also on the Quadrants
