To the teacher:
Many acitivites are self-explanatory
and contain follow-up questions. Answers to the questions are
found within the explanation. Consider requiring students to copy
the explanatory paragraph as part of the follow-up activity. Because
of the nature of these activities grades can be based on a 5 point
scale. Perfect papers receive 5 points (A), 4 points (B), 3 points
(D). After a few low grades students usually begin to read the
explanation carefully before answering the questions.
