Overview:
Our lessons are designed in such a way that you can pick one lesson that
fits in
with your curriculum. These lessons also work well when you can not avoid a
substitute teacher in your room. The lessons are self guided and will al low for
classroom discussion at a later time.
The lessons are designed to have students investigate
Graph Theory , Counting
Principles, Venn Diagrams, Least Common and Greatest Common Multiples ,
Greedy and Nearest Neighbor Graphs.
We hope you enjoy the selections we put together and they
enhance your classes.

Activity
The students should work with a partner. They are to as sume that they are at
a party
with 9 other friends (total of 10 including themselves) and they want to get a
picture of
themselves and one other person but they want a picture of two with everyone .
Each student
will complete the following tasks:
1. Make a graph to represent how many pictures need to be taken.
2. Decide how many pictures total are taken, not including duplicates.
3. Repeat steps 1 and 2, but for 3, 4, 5 and 6 people in each picture.
4. Record there results in some organized method so they can present it to the
entire
class.
5. Write a rule or method they would use to determine total possibilities if
there
were nth number of people at the party.
6. Share results with entire class.
Extension
Have students determine how many possibilities for seating charts in their
classroom ,
since some are never satisfied with the seating chart the teacher makes for the
class. This
could lead into classroom management and behavior for your
class.
