Team 1, Session 4: Notes

==Other teams==
 54  ModeratorSf, 20:07 (19.05): We are ready to start. Today, you can finish the work that you have been doing as a team 
                                 in the previous three sessions. There are five teams in this project and they have all explored very 
                                 interesting questions about the ?grid-world? that we started with.

==We came to a solution for the one last time==
 69  ModeratorSf, 20:14 (19.05): you can continue the problems from last time or we can try another, what you say?               
 70  mathpudding, 20:16 (19.05): try another          
 71  TinyFryhiii12, 20:15 (19.05): another     
 72  mathman, 20:16 (19.05): another we came to a solution for the one last time
     ModeratorSf 5/19/05 8:15:34 PM EDT: ok
     ModeratorSf 5/19/05 8:16:01 PM EDT: i'll put it on the whiteboard
  
  Textbox on the whiteboard:
  Here is a problem to work today or, why not, with your friends this summer: 
  You might wonder what you get if you find all of the points that are the same distance 
  from a given point and then connect them (with the shortest path). In regular geometry 
  this would give you a circle. What would you get here? What would be the ratio of circumference 
  to the diameter? In regular geometry it is always the same number, pi.
   
  ...
  ModeratorSf 5/19/05 8:20:05 PM EDT: so, you see that, in some way there is a link to the previous problems...
  mathman 5/19/05 8:20:21 PM EDT: yes

==Moderators attempts grid frame==

  ModeratorSf 5/19/05 8:46:26 PM EDT: hey, guys, do you recall that you cannot go on diagonals
  mathman 5/19/05 8:46:41 PM EDT: what do you mean by that??
  ModeratorSf 5/19/05 8:47:10 PM EDT: in the grid world you can only travel on the lines of the grid
  ModeratorSf 5/19/05 8:47:25 PM EDT: and distance is accordingly....
  mathman 5/19/05 8:48:51 PM EDT: now i see what you mean
  mathpudding 5/19/05 8:50:30 PM EDT: who put triangles
  mathpudding 5/19/05 8:50:55 PM EDT: whos blue
  templar 5/19/05 8:51:07 PM EDT: i did
  mathman 5/19/05 8:51:13 PM EDT: oh
  mathpudding 5/19/05 8:52:30 PM EDT: stay on the grid lines
  mathman 5/19/05 8:52:35 PM EDT: yes
  mathpudding 5/19/05 8:56:48 PM EDT: wat now?
  mathman 5/19/05 8:57:07 PM EDT: why dont we try inscribing a square within
 
Participants use diagonal distance but try figures that "stay on the grid:" a squere, a rectangle, etc.

==Calling everybody to respond==

  mathman 5/19/05 9:02:55 PM EDT: anymore ideas
  mathpudding 5/19/05 9:03:07 PM EDT: ?
  mathman 5/19/05 9:03:16 PM EDT: templar?
  templar 5/19/05 9:03:27 PM EDT: i ran out of ideas a while ago
  mathman 5/19/05 9:03:29 PM EDT: TinyFryhiii12?
  mathpudding 5/19/05 9:03:31 PM EDT: TinyFryhiii12?
  mathpudding 5/19/05 9:03:45 PM EDT: is she there?
  TinyFryhiii12 5/19/05 9:03:54 PM EDT: yea
