Are you short of funds for
purchasing three dimensional models? Are you short of
funds for purchasing computer software for 3-D demonstrations?
Don't give up! Simple and inexpensive manipulatives may be
able to help.

Using an Open Crate
An open crate, such as the one at
the right, can become an inexpensive manipulative for examining
lines and planes.
The sides of the crate can
illustrate the relationships between parallel planes and
perpendicular planes.
|
|
| The open nature of
the crate allows for lines (rods, pencils, rulers, yardsticks,
straws, string pulled tight) to be passed through the openings so that relationships
between lines and various planes can be observed.
Students can work with a crate at a station
during review, as a class activity, or as observers as the
teacher demonstrates. |
| Using the Classroom Walls
The walls and ceiling of the classroom can
illustrate the relationships between parallel planes and
perpendicular planes. Students, yardsticks, rods, poles,
brooms, etc. can act as lines and can be positioned in various
locations to illustrate theorems about lines and planes. |
|
| Using the Exterior
Walls
The exterior walls the school building can
also illustrate the relationships between parallel planes and
perpendicular planes. A picture of your school building
can be used on worksheets to illustrate planes. Just label
the picture and you are ready to ask questions about planes. |
