STEPS Set Induction (10 minutes)

CONTENT Revision : To multiply two linear expressions.

Step 1 (20 minutes)

Introduction : To form quadratic expression by multiplying any two linear expressions.

Step 2 (20 minutes)

Development I : To multiply two linear expressions to form a quadratic expression.

TEACHING AND LEARNING ACTIVITIES 1. Teacher discusses the basis of multiplying two linear expressions by giving two simple examples. Example 1 x (2x) = 2x2 Example 2 x(x + 3) = x2 + 3x 2. Teacher raises the level of difficulty by asking, “How do you multiply (x + 2)(x – 5)?” 3. Teacher shows the method of multiplying (x + 2)(x – 5). 4. Students are then asked, “How do you multiply (2x – 5)(3x + 7)?” 1. Students form two groups. 2. Group A gives a linear expression and group B gives another linear expression. A student from group A then multiplies the two linear expressions to form a quadratic expression. Teacher determines whether the quadratic expression is correct. 3. Subsequently, Group B gives a linear expression and group A gives another linear expression. A student from group B then multiplies the two linear expressions to form a quadratic expression. Teacher determines whether the quadratic expression is correct. 4. After each group has formed ten quadratic expressions, the group with the highest score is the winner. 1. Students are asked to refer to Example 2 and Work This Out on page 21 of textbook. 2. Teacher explains Example 2 on multiplying two linear expression to form a quadratic expression. 3. Students are then asked to try Work This Out on page 21 of textbook.

REMARKS Recalling Students learn by recalling what they have previously learnt in early subtopic.

Mastery learning Students master the technique of multiplying and factorizing algebraic expression.

Constructivism Students apply prior knowledge to new situations

Step 3 (20 minutes)

Development II : To form quadratic expressions based on specific situations.

Closure (10 minutes)

Conclusion : To form quadratic expressions based on specific situations

1. Students form group of four. i) Students are asked to refer to Maths Inquiry 2(Textbook, page 22) ii) Each group tries to form quadratic expressions from the given situations. iii) Each group presents their answers on the black board. 2.aTeacher discusses Example 3 (Textbook, page 23) and Work This Out (Textbook, page 23). 3. Teacher discusses Example 4 (Textbook, page 23) and Work This Out (Textbook, page 23). 1. Students are asked to try answer the first question in Exercise 2.1 C. 2. Students are shown the method to answer the question in Exercise 2.1 C. 3. A students is asked to compare their answer with teacher’s answer. NOTE : Homework : Exercise 2.1 C (Textbook, page 23)

Cooperative learning Students pool resources to acquire knowledge

Self-access learning Students acquire knowledge and skills independently.
