A
dd variety to the two-point theme.
This exercise, like the preceding one, is easy in that you will have done the reading for
them. (You will have isolated the three most important points from the passage.) Again, you will
point out the two most significant points made in the reading passage. Then you will admit that
there actually were three points. It is their task to skim the material and isolate the third
significant point.
Form triads and have them share their most significant third-points. Encourage them to vote on
the one point that is clearly more salient than the other two.
If any group has three members who have all made the same selection, ask them to explain the
rationale behind their choice. Otherwise, call on groups at random to share the point that was
ranked at the top by the members of that triad.

ave them create headlines.
This exercise will develop their ability to synthesize. It asks that they divide the material into
four or five sections. (You will have determined that number in advance.) Then, they are to
create a heading for each section, a heading that encapsulates the information contained in that
section.
Brainteaser:
Four students—Alex, Bob, Charlene, and Desiree—had this to say about a
number they were shown:
Alex: It has two digits. Bob: It goes into 150 evenly.
Charlene: It can be divided by 25. Desiree: It is not 150.
One of the four students is mistaken about the number. Can you tell which one?
Answer: Desiree has the wrong information. If Alex were mistaken, the number would have three digits. If it did, either Bob
or Charlene would have to be mistaken, because 150 would be the only three-digit number that would go evenly into 150.
Therefore, Alex must be correct, because there is only one mistaken person.
If Bob had the wrong information, then the number does not go into 150. But then either Alex or Desiree must be mistaken,
because the only two-digit numbers that can be divided by 25 all go evenly into 150. So, Bob must be giving accurate
information.
If Charlene were wrong, then the number would be 150. But then Alex would also have to be wrong, because 150 has three
digits, not two. And we know Alex is correct. So that leaves Desiree.
