Slide 12 of 61
Notes:
Before moving on to the next slide see if you can exchange the two groups of students. You might want to use the Secret Passageway Template and house flags to simulate the problem. Copies of these manipulatives can be found at http://home.ptd.net/~judyann/nctm2003.
If you can not solve the problem with 6 students, try a simpler problem. What moves would you take if there were only 2 students involved? What about 4 students? Look for a pattern.
