First meeting
Introduction (± 5 minutes)
(Phase 1: Clarify goals and establish set)
1. Teacher generally presents the learning objective that is finding the formula
of surface area of cylinder and cone
2. Apperception: Leads the students to recall the material that had been
learned before and correspond with the material that will be discussed such
as the area of rectangle and circle.
3. Motivation: Motivates the students by relating the material that being
discussed with real life situation, for example:
Main Activities (± 60 minutes)
(Phase 2: Present information)
4. Teacher reminds students about the area of rectangle and circle and cylinder
and cone net. Then, the teacher tells to students that they are going to find
the formula of surface area of cylinder and cone.
(Phase 3. Organize students into learning teams)
5. Teacher divides the class into 5 heterogenic groups.
6. Teacher gives a worksheet to each group and asks them to do the
worksheet.
7. Teacher tells the students that after doing the worksheet they have to
present their work in front of the class.
(Phase 4. Assist teamwork and study)
8. Teacher assists each group as they do their worksheet.
9. One of each groups presenting and explaining their group report and some
student in other groups give comment to it
10. The students and the teacher discuss about the right answer
11. The teacher asks to the students about the first problem solving
12. The students answer problems by their own ways
(Phase 5. Test on the materials.)
3. 13. Teacher give a quiz to students to check students understanding
Closure (± 15 minutes)
(Phase 6: Provide recognition)
14. Teacher gives feedback and appreciates the result of every group.
15. Teacher gives a reward to the best group that has the best score.
16. Teacher give home work to the students.
