Introduction
This exercise will take you on a fun-filled quest. Kryssy the archaeologist, needs your help to unlock the key which will open the cave and unlock the treasure chest. The problem is that, in order to get this key, Kryssy has to identify 3-D solid shapes by their nets or by their characteristics in order to assemble the shapes to insert them into the correct section in the wall to unlock the key. Sadly, Kryssy doesn't know which is which.
In groups of three, you can help Kryssy the archaeologist, but in order to do so, you must be able to identify each shape by knowing how many faces, edges and vertices it has, as well as how their nets look before they are assembled. This may get a little confusing at times, but think really hard so you can be of great help to Kryssy...
Task
Create a presentation that will help Kryssy to understand the description and characteristics of each solid shape needed for the mission along with a picture of the outline of the nets.
Be sure to help Kryssy the archaeologist, name and identify all of the solids. Have FUN!!!!
Process
In groups of three students will identify and present with the aid of PowerPoint slides and physical
manipulatives the following figures: cylinder, rectangular prism, sphere, cone, cuboid and cube. For
each of the figures students should:
- Write a description of the object and the matching geometric figure along with its net, answering the following questions:
- What are the characteristics of this geometric figure?
- What are some real-world objects that represents these shapes?
- What are the cross-sections of these shapes?

Identifies some objects but has no real world examples |
|
Eye Contact |
Holds attention of entire class with the use of direct eye contact, seldom looking at notes. |
Consistent use of direct eye contact with audience, but still returns to notes. |
Displays minimal eye contact with audience, while reading mostly from the notes. |
No eye contact with audience, as entire as all the information is read from notes. |
|
Content |
Clearly list all properties associated with all the figures chosen. |
Lists at least 3 properties associated with the figures. |
Lists at least 2 properties associated with the figures. |
List no properties of the selected figures. |
|
Deportment |
Movements seem fluid and helps the audience visualize concepts while displaying relaxed, confidence with little or no mistakes. |
Fair amount of movements or gestures that enhances articulation. Makes minor mistakes, but quickly recovers and displays little or no tension. |
Minimal movements or descriptive gestures. Displays mild tension; has trouble recovering from mistakes. |
No movement or descriptive gestures. Tension and nervousness is evident; has serious trouble recovering from mistakes. |

Presents information in logical sequence which class can follow. Presentation has no more than two misspellings and/or grammatical errors. |
Class has difficulty following presentation because students are jumpy. Presentation has three misspellings and/or grammatical errors. |
Class is unable understand presentation because there is no sequence of information. Student’s presentation has four or more spelling and/or grammatical errors. |
Conclusion
I hope you are now able to make all the possible nets of 3D shapes in order to help out Kryssy.
