Hi,

    I would like to thank you for presenting such an interesting question or we can say challenge about recursion.

    Your instruction is very clear. Besides, the scientific background and explanations about recursion are concise and understandable. Further, what I treasure most is your attempt to adapt the concept of recursion to different situations. This indeed shows the spirit of mathematicians.

    Your work is excellent; however, I still want to make some comments and recommendations:

1. Because of my lack of knowledge in recursion, it takes time for me to figure out the question and the solution raised in the video. It would be more audience-friendly if the authors give more information about the background knowledge of recursion.
2. The background knowledge mentions about Tower of Hanoi and Russian nesting doll. It would be more clear if the authors clarify them a little bit more.
3. The process of thinking is important. My biggest concern is that the example video does not show the process of inquiring as the video focuses on the solution, which means there is little time for the audience to think of the question.  

  Thanks again for such an excellent work!

This video is very good example of teaching recursion. 

  1、This structure gives a vivid explanation of recursion. 
  2、In the video, the process of moving disks is clearly showed. 

Apart from the many strength of this project, there are also some challenges. 

  1、The creators may make the video with more special effects to attract the           attention of the students. 
  2、In the video, disposal cups are used to represent disks, but maybe the authors can     used tools that are more similar to disks in appearance. 
  3、I think maybe this project can also add more fun to it. For example, there is a       story of moving 64 disks in a very big Hanoi, a question can be given to the students     like how long it may take for people move these 64 disks from one pillar to another. 

Thank you!

sencerely!

I really liked the idea of the movie, I believe that kids like riddles, and even more they like to solve riddles. The riddle you gave about saving the family describes well the idea of recursion, you did very well when you added the grandfather and showed the recursion step. I think that you could have explained more about this recursion step and ask at the end a question regarding this step, like “can you describe the recursion step ?” and then gradually add another person and after that 2 others and so on.

One small correction, in the rules of the Hanoi tower the first rule should be “only the most upper disk of the piles can be moved”

Thank you for your work and idea,

Tomer
