Scaling the Teaching Curve: A PCMI Teacher Program Residential Workshop Tuesday, July 30 Photos Math 4

Math 4 (Tuesday morning)
We considered three kinds of restricted trains: (a) trains with only length 1 and 2 cars, (b) all car lengths except 1, (c) only odd length cars. For each type, the count of all length n trains was a Fibonacci number. In each case, we showed that the restricted trains satisfied the Fibonacci recurrence. Then we worked on direct connections between the three types of restricted trains.
