STUDENT’S PRESENT LEVEL OF PERFORMANCE AND KNOWLEDGE:( Do the students have the adequate knowledge to complete the lesson successfully? What pre-requisite skills must the students have to complete the lesson content? Include technology skills.)

Pre-requisite skills needed:

1. Knowledge to sketch graphs, ie the general shape of the graph as well as the essential

points needed when applicable.

2. Knowledge of the use of the software, Graphmatica.


INSTRUCTIONAL PROCEDURES:

1. Motivation:

Explain the importance of the lesson to motivate the student. Relate lesson to previous lesson or real-life situation.

This is an important topic in Mathematics as many real-life situations can be represented using graphs.

If we have all the essential points, ie x and y intercepts, maximum or minimum points, a line or curve can be sketched.

2. Activities: (The sequential activities to happen in this lesson. It describes the teaching method to employ in learning the lesson.)

Get the students to settle down in class.

Recall past knowledge about the sketching of line and curve, ie the general shape of the curve and the essential points required.

Teacher to give out worksheet to the class. Teacher to get the class to start their computer.

Extract from the worksheet:

Teacher to tell the class that they are going to Interpret the shape of the graph based on the function for

. Teacher to ask the students to do the first 3 pages of the worksheet given to them.

They are to explore the graphs, for , using the Graphmatica software and answer the

questions.

The teacher to go through the questions with the students. Teacher to get the students to recall past knowledge that is related to these 3 graphs.


1. is a horizontal straight line passing through a.

2. is a straight line passing through the origin.

3. is a quadratic curve. The line of symmetry for the curve is a vertical

straight line passing through the maximum or minimum point.

Teacher to ask the students to continue with the worksheet, pg 4.

Teacher to go through the worksheet with the students. Introduce a new term to the students: point of inflexion.

Teacher is to elicit to the students why the general shape of the graph of is as such.

Teacher to get the students to continue with the worksheet, pg 5-8. Teacher to go through the graph of

and . Through the guiding questions given in the worksheet, the teachers will explain to the students why

the general shape of the graphs is as such.

3. Closure:

Teacher to summarize what the students have learnt today by going through pg 7-8 of the worksheet. Teacher to

pick students to come to the board and draw the general shape of for .

SUPPLEMENTAL ACTIVITIES:

1. Additional activities to expand the lesson2. Remediation activities for the student needing more instruction and practices3. Assignments

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.

During discussion, the teacher can pick on students to answer question. Can correct any misconceptions if they have any. For the summary of what they have learnt today, the teacher can also check for understanding by picking out weaker students to sketch the general shape of t

for .

STUDENT PRODUCTS:

What artifact(s) or products will result from the lesson? (such as a report, newsletter, diagram, slideshow, drawing, etc.)

Completed Worksheet to be submitted for checking.

2. The graph of is defined for all real values of x, except when x = _______. Therefore, the ____ - axis

is known as an ____________ .

3. There is _____ turning point for .

4. As the positive value of x increases, the value of will ___________. Hence, the value of y

___________ . The curve will get very close to the x-axis but it will never touch it.

y


5. Between , the gradient of the graph has a very __________ gradient. This is due to the rapid

______________ in the value of y.

6. As the value of x becomes more negative, the value of becomes _________ negative. Hence, the value

of y becomes _________ negative.

7. Between , the gradient of the graph has a very __________ gradient. This is due to the rapid

______________ in the value of y.

8. The 2 parts of the graph are mirror images of each other. There are 2 lines of symmetry for . The

equations are ______________ and ______________.


e. Case n = - 2


1. 2. 3. 4.



2. The graph of is defined for all real values of x, except when x = _______. Therefore, the ____ -

axis is known as an ____________ .

3. There is _____ turning point for .

4. As the positive value of x increases, the value of will ___________. Hence, the value of y

___________ . The curve will get very close to the x-axis but it will never touch it.

5. As the value of x becomes more negative, the value of becomes _________ positive. Hence, the value

of y becomes _________ positive.

6. Between and , the gradient of the graph has a very __________ gradient. This is due to

the rapid ______________ in the value of y.

7. Since the values of y are always positive, therefore the curve lies entirely _________ the x –axis.
