square?”
b) Discourage students from making conjectures.
c) Regularly give them vocabulary spelling quizzes.
d) Make sure that there is lots of time between class discussions, so they don’t get overwhelmed by
all the new vocabulary.
TRUE/FALSE. Write “T” if the statement is true and “F” if the statement is false.

TRUE/FALSE. Write “T” if the statement is true and “F” if the statement is false.
14) The algebraic topic of “slope” should not be discussed with students until they learn about equations.
15) Class time should only be devoted to developing visualization if it’s available after learning all needed
vocabulary.
MULTIPLE CHOICE. Choose the one alternative that best completes the statement or
answers the question.
16) Polyhedrons
a) Are a family of 3D shapes that include spheres
b) Are “completely regular” if every face is a regular polygon and every vertex has the same
number of faces joining at that point.
