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
