SURFACES
MTH 254

We will make frequent use of clear plastic surfaces to illustrate geometric concepts.

Getting a surface:

• Surfaces are available for checkout from Judy in the Honors College office.
• Please fill out the information on the checkout list, including your name, the date, and the color of your surface.
• Please ensure that the rolled-up plastic mat you get at the same time has the same color dot in the corner.
• You will also get a gadget that looks like a compass, called an inclinometer.

Caring for your surface:

• Surfaces are fragile! Please treat them gently.
• Please do not fold the mats! Roll them up if you are not able to store them flat.
• You may write on the surfaces and mats with dry-erase markers only!
• Please write only on the clear plastic tops of the surfaces, not on the sides or bottom.
• You can erase using a soft paper towel, paper tissues, or a soft cloth.
• For persistent stains, alcohol works well.
• Please erase your surfaces and mats after every class.

Returning your surface:

• Please return your surface, mat, inclinometer, and other supplies to the Honors College office at the end of the term.
• Please enter your initials and the return date on the checkout list.
