GRADE K-3 / Ages 5-8
Peg A Peg B Peg C
There are ten disks sitting on Peg A. The disks are increasing in size, the largest disk sitting at the bottom, on top of this a smaller disk, on top of that a still smaller disk, and so on. We may take disks off a peg, always one at a time, and put each disk on another peg. However, we can NEVER place any disk on top of a smaller disk. Here is your problem: transfer all the disks from Peg A to Peg B.
Answer the following questions:
A) How should this be done?
B) What is the least number of moves that we must make to transfer all the disks from one peg to another?
