Whiteboard Session

Today I participated in a whiteboard session from the JHU CTY Math Olympiad Course. A whiteboard session is a class on the computer using Adobe^® Connect. There were four other 4^th graders that participated in that session – Phil, Damon, and Manya. We talked a lot on the chat board, which I enjoyed the most. I enjoyed the chat board because it was very lively. Phil was annoying; he kept saying “okkookko”, “okokokokokok”, or “BYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY YYYYYYYYYYYYYYYYYYYYYYYYYYE!!!!!!” I liked talking about the teacher – I would always tell everybody when she was disconnected from the internet again. The problems were tricky. One problem asked: “Every two people at a banquet were served a chicken dish, every three a rice dish, and every four a vegetable dish. If there were 65 dishes, then how many people attended the banquet?” I solved the problem by finding the LCM of 2, 3, and 4, which are 12. 12/2 is 6, 12/3 is 4, and 12/4 is 3, so every 12 people were served 13 dishes. If 12 people equals 13 dishes, then 60 people equals 65 dishes. I had a really hard time at first, because I used the wrong method.
