project on oragami and polyhedral

2) Benefit of the project:
• It is a hands on activity
• Helps students to visualize the 3 dimensional worlds. For instance, how many vertices there are, finding information about edges, sides, and etc?
• Avoids boredom in the classroom and incorporates other subjects such as Arts.
• It makes students familiar with the background and history of polyhedral.

Weaknesses of the project:
• The project is indeed very time-consuming due to making origami. That might be annoying for students and as a result it might leads to frustrations and confusion. Furthermore, students might loose their interest toward the subject.
• Time wise, might be hard to fit this project in the curriculum.

Uses of the project :

• Making the students to feel for 3-D world.
• Make them familiar with what geometry is, in particular polyhedral.
• It might be a fun classroom activity to follow.

How to modify the project:

• We can avoid making the students to do the origami in the classroom.
• Give them other options for origami. For instance, cut the segments and tape them together. This way, it is less time consuming and it gives the students the same result.

Extension of the project:

• We can ask our students to think about volume, surface area, and some other physical properties such as the number of edges, angels, and etc afterward, or for future



3) Our project (Surface Area):

• Grade level : Grade 9

• Purposes: To make a fun activity in the class, avoid boredom about the teaching subject, make the students to get a notion for a 3-D object/world, practicing the concept of “Area” in mathematics.


• Description: There are two choices for this project:

1. Students must build a “Reasonable” shape object such as a house, car, flower, and etc using at least two 3-D objects.
2. Or build a complex structure using only one 3-D object of their choice.

Students must choose only one of the above options. For either one they must follow the below criterions.(2-3 people per group)

o Students must hand in an informal proposal for this project.
o They must build the structure.
o They must write a report including the followings:

i) How they got the surface area of the object they made in details. This includes a verbal explanation and diagrams.
ii) Measuring and calculating the surface area of the object in two different units. ( cm, and mm)


• Time:
o First session: 20 min for proposal in the class.
o Second session: A full class time for material and making objects.
o Giving them a week for the final work.

• Production:
o Reports and structures.




• Marking Criteria:
o Communication ( how well they explain the work)  35%
o Calculations(how they got the surface area and units)  50%
o Structure ( what they made)  10%
o Creativity 5%
