This lesson plan is for a secondary 3 mathematics class on coordinate geometry. Students will learn about the gradient-intercept form of equations for straight lines (y=mx+c) through interactive online activities and games. They will work individually on computers to complete worksheets exploring the meanings of m (gradient) and c (y-intercept). Formative and summative assessments include a quick check, online quiz, and final exam questions to evaluate student understanding of key concepts such as plotting points and interpreting line equations.

Name of Teacher: Mrs Susan Ng
LESSON TITLE: TIME ALLOTTED:
Coordinate Geometry : Equations of straight lines 1 hour
LESSON DESCRIPTION: (Write a concise description of what occurs in this lesson.)
In this lesson, the students will learn how to express the equation of a straight line in the gradient-intercept form
( y = mx + c, where m – gradient and c – y-intercept. )
CLASSROOM LAYOUT AND GROUPING OF STUDENTS:
(Where will the learning take place? How will the room be organized with the computers? How will the students be
grouped (class group, individuals, pairs, small groups, etc…)
Students will work individually in the computer lab.
INSTRUCTIONAL OBJECTIVES:
(Identification of the specific learning outcomes expected to happen based on Competency Standards.)
Students will learn the concept of slope and y-intercept of a straight line through operating in an interactive media
environment.

INSTRUCTIONAL PROCEDURES:
1. Motivation:
Concept of points, slope and equation of straight line in coordinate Geometry have always been abstract and
difficult for the lower ability students.
Through the use of interactive math games, students will be able to handle the concepts more confidently.
Moreover, the fun element in the math games took away the ‘dryness’ of the concepts.
2. Activities: (The sequential activities to happen in this lesson. It describes the teaching method to employ in
learning the lesson.)
10 mins : Recap on concept of gradient and how to calculate it.
http://hotmath.com/help/gt/genericalg1/section_2_4.html -direct student to the URL
20 mins : Students will be introduced the linear equation y = mx + c
With the help of the Spreadsheet ( Exploring m and c ), the students will complete Worksheet 1.
10 mins : Students to share observations made and deduce the meaning of ‘m’ and ‘c’.
15 mins : Students to consolidate what have been learnt.

3. Closure:
5 mins : Teacher to close lesson by reinforcing that the meaning of m and c in the equation
Teacher will also inform class that students will learn how to find equation of a straight line using the
point-gradient method in the next lesson.
SUPPLEMENTAL ACTIVITIES:
1. Additional activities to expand the lesson
2. Remediation activities for the student needing more instruction and practices
3. Assignments
Students will be told to prepare for a Quick Check for the next lessons
Students will also be attempting a online Quiz administered through ACE-learning platform.
Additional websites for them to consolidate their concepts will also be given:
Plotting points with Graph Mole ( 3 levels)

ASSESSMENT AND EVALUATION:
How will you measure the student’s success? Formally or informally? Formal evaluation of student work requires that
a grade is taken while informal might be monitoring of work, or class discussion. This section should contain a
description of the assessment process, the criteria for achievement, and performance levels. The criteria should
directly align to objectives and instruction. Describe your plan for providing feedback to your students.
A Quick Check on student’s understanding of points, gradient, distance and meaning of m and c will be given before
the start of the next lesson (final lesson of the unit) – this will allow the teacher to make assessment on what to
reinforce when teaching the last segment.
A Quiz will be administered using the ACE-Learning platform to test the mastery level of the students.
A formal assessment will be also be given to test students’ understanding of the whole topic.
STUDENT PRODUCTS:
What artifact(s) or products will result from the lesson? (such as a report, newsletter, diagram, slideshow, drawing,
etc.)
