I learned today, after working on a geometry unit with my 7th grade math class for the past three weeks, that the radii of a circle are all *arcs*, and that an equilateral triangle has *four* sides.

These were answers to multiple choice questions.

According to the California 7th grade mathematics standards, I'm supposed to be teaching them to calculate surface area and volume of simple geometrical solids. How can I do that when they won't even TRY to remember how many sides a triangle has?
