Direct Instruction
G.Learning Activity
First meeting
Introduction (± 5 minutes)
(Phase 1: Clarify goals and establish sets)

2. 1. Apperception: teacher reminds students about the materials that are related
with the materials will be learned.
2. Motivation: teacher Teacher gives some examples about non polyhedron in
daily life, and gives an example about problem solving using this material.
Tia is going to have a birtdhday party. She will
makes a party hat in conical figure as shown in
thepicture on the left. If the height of the hat is
16 cm and the radius is 12 cm, how wide is the
paper needed for one hat?
To solve that problem, we need to know the
elements of cone and we also must draw the
cone net before we make it as a party hat.
3. Teacher informs the learning objectives
Main Activity ((± 70 minutes)
(Phase 2: Present information)
4. Teacher explains the definition of a cylinder, a cone and a sphere.
(Phase 3: Organize students into learning teams)
5. Students are divided into groups of 4-6 ( become six groups )
6. Teacher gives worksheet.
7. Teacher asks the students to do the worksheet in group
(Phase 4: Assist teamwork and study)
8. Teacher observes and help the group that get difficulties to finish the
worksheet.
9. Teacher gives a reinforcement and feed back
(Phase 5: Test on materials)
10. Teacher gives a quiz to check students understanding
Closure (± 5 minutes)

learned.
Second meeting
Introduction (± 5 minutes)
(Phase 1 : Clarify goals and establish sets)
