This document outlines mathematics teaching plans for two lessons: (1) using clinometers to measure tree heights as an application of trigonometry, and (2) identifying cube and rectangular prism nets. For the first lesson, students will learn about clinometers and trigonometry, then work in groups using clinometers to measure tree heights from different distances. For the second lesson, students will learn the characteristics of cubes and rectangular prisms, then draw and construct examples of nets for these 3D shapes. Both lessons aim to develop students' cognitive, psychomotor, and affective skills through hands-on activities.

2. Topic :Trigonometry
Class : X – Senior High School
Function : Applied Trigonometry in daily activities with using clinometer
Activity :
Teacher explain about trigonometry concept and then teacher
explain about how to use a clinometers and what is the formula to
find the height of the tree. Divide students into 4 – or 5 person
groups and they try to observe it with difference distance or
difference observer
Height of the
tree
Height of
the
observer
Distance between the observer and the object
Cognitive Development :
1. Knowledge : Students remember how to use clinometers, concept
trigonometry, and formula to find the height of tree
2. Comprehension : Student explain to their friends who doesn’t
understand yet and discuss with friend in their groups.

3. 3. Application : Student apply procedure how to use clinometer, and
apply the formula to find the height of object
4. Analysis : Students compare every result of observing with
difference distance or difference observed
5. Evaluation : Students justify every result of observing from the
other groups
6. Creating : Student able try to observe the taller object by
her/his self
Psychomotor Development:
1. Observe : Students want to participate
2. Model : Students are able to follow how to use clinometer and
how to find the height of object like teachers demonstrating last.
3. Recognize Standard : Student are able to perform their skill and task
correctly and this observing quickly
4. Correct : Student do more observing to prove and test their
result is correct
5. Apply : students can do this observing with others object in
the environment around the school
6. Coach : Observer are able to demonstrate their observing to
the other friends.
Affective Development:
Affective development can be looked by student’s respond of this activity.
Student respect to that observing and want to study and discuss this
obseving in their group. Student able to cooperate in the group and can
measure the height of the object and use the clinometer accuratly,
patiently, be brave and interested to try.

4. Topic : Cube and rectangular prism nets
Class : VIII – Junior High School
Fungtion : To know and indentify some form of cube and rectangular
prism nets
Activity :
Teacher has explain about the definition and characteristic of cube
and rectangular prism and then teacher has assign students to bring a
carton, pencil, eraser, scissor, and ruler . Then teacher give
instruction to students to draw the cube and rectangular prism nets
and teacher give an example of them.
Cognitive Development:
1. Knowledge : Student know and remember the characteristic of the
cube and rectangular prism.
3

5. 2. Comprehension : Student identify the cube and rectangular prism
nets and explain to her/his friend who doesn’t understand yet and
he/she understand how to create cube and rectangular prism net.
3. Application : Student apply procedure how to draw sketch and
create cube and rectangular prism nets. Student prove the
characteristic of cube and rectangular prism.
4. Analysis : Student compare every form of cube and rectangular
prism net
5. Evaluation : Student conclude the activity of drawing cube and
rectangular prism nets
6. Creating : Student make the new form of cube and rectangular
prism net
Psychomotor Development:
1. Observe : Students want to participate to create cube and
rectangular prism nets.
2. Model : Students are able to follow how to draw and create
cube and rectangular prism nets
3. Recognize Standard : Student create cube and rectangular prism
nets.
4. Correct : Student are able to check the cube and rectangular
prism net with create it be a cube or rectangular prism correctly and
student do it again, if their cube and rectangular prism net that has
created is not correct
5. Apply : students can construct design and create the different
cube and the rectangular prism nets
6. Coach : Student are able to demonstrate their cube and
rectangular prism nets

6. Affective Development:
Affective development can be looked by student’s respond of this material
and also views of the willingness of students to bring the tools that teacher
had assigned. Student is enthusiastic in this activity and teachers can see
how they make it . Student able to create cube and rectangular prism net
accuratly, patiently, and they want to try the different form of cube and
rectangular prisms net.
