Teacher's Name: Lorna B. Abellana School Name: Mayor Anunciacion R. Tuazon National School of Fisheries School Address: Calunasan, Calape , Bohol Topic: Solving Systems of Linear Equation in Two Variables by Graphing Year Level: Second Year Objectives: A.Subject Learning Area: 1. At the end of the lesson the student should be able to distinguish among the three kinds of systems of linear equation in two variables based on the following a.slope b.number of solutions c.graph d. ratio form
2. At the end of the lesson the student should be able to identify those whose graphs intersect, coincide, and are parallel , given a pair of linear equation in two variables.
3. At the end of the lesson the student should be able to draw out the solution based on the coordinates of the intersection of the graph. B.ICT Learning Area : 1. At the end of the lesson the student should be able to access and retrieve appropriate information from the internet.
2. At the end of the lesson the student should be able to communicate with a targeted audience by using such communication technologies as e-mail and web browsers.
3. At the end of the lesson the student should be able to demonstrate an understanding that information can be transmitted through a variety of media.
4. At the end of the lesson the student should be able to create a plan for an inquiry that includes consideration of time management. Class Duration: One (1) Hour ICT Tools/Resources:

Pre-requisite Skills:
1. The student has the initial knowledge on how to find the coordinates of a point. 2. The student has the ability to graph linear equations in two variables using slope and y intercept.
3. The student's basic knowledge on how coinciding lines, parallel lines, and intersecting lines look like. Preparations: Before the class the following must be done:
1. Check the availability of computers with LAN 2. http://lgfl.skoool.co.uk/viewdetails. 3. The student will be assined to group activities. 4.
