Teaching and Learning Activities
1.
Introduction(10 minutes)
Step 1: Clarify goals and establish set
Apperception : By question-answer, the
students are reminded of one variable linear equation system, example:
Dani and Ida are brother and sister. Ida is
8 years older than Dani. Today Dani is exactly 5 years old. How old Ida?
Can you make model of that statement?
Teacher tells the
learning objective
Motivation : The
teacher give example of LETV that has
connected with daily life.

II. Main Activity (60 minutes)
Step 2: Demonstrate knowledge and skill
Ø
Teacher ask students to discuss about example of
LETV above in pairs
Ø
Teacher give guidance to the students in discussing process
and help students if they have problem
Ø
Teacher guide discussion into LETV
Ø
Teacher give examples about LETV and ask student randomly to
give another example
STEP 3: Provide guided practice
Ø
Teacher give problem about LETVS
Ø
Teacher ask students to discuss about example of
LETV above in pairs
Ø
Teacher give guidance to the students in discussing process
and help students if they have problem
Ø
Teacher guide discussion into LETVS
Ø
Teacher give another example of LTEVS
Ø
Teacher guidance discussion into difference of
LETV and LETVS
Ø
Teacher give example LETVS on various form and
variable
Step 4: Check for understanding and provide feedback
Ø
To check student’s comprehension, teacher asks students to
do students’ worksheet individually
Ø
Teacher around the class to observe student’s progress,
and help students if there are some problems
III.
Closing ( 10 minutes)
Step 5: Provide extended practice and transfer
Ø Students collect their worksheet
Ø By question-answer, teacher guide students to make summarize the
subject material that were studied.
·
LETV is equation that have 2 variable
·
If there are two LETV, so that are called LETVS
Ø Teacher give students homework
Ø Teacher asks students to study
next material
E.
Evaluation
·
Technique : Written test
·

Open
ended answer. Example of LETVS: p – 4q + 2 = 0, 3x + 15 = 3y
Example of LETVS: 2p – 5q = 2 and p + 5q = 6, 2x +
5y = 8 and x + 5y = 2,
y = 2x –
5 and y = x + 3
