ENTRY 3 Back in class we used the data we had collected on the bridge to answer our question. Here's what we had: A car was 14 feet 8 inches long, on the average. The distance between the beams we had measured was 14 feet. So, we figured that that was pretty close to one car fitting in between 2 beams. There were 3 lanes of traffic in each direction, so there were 6 lanes altogether. We counted 258 beams on the bridge. The distance between the beams was 14 feet, which we are saying is equal to 1 car's length. Not width! So here's our formula:
 Two hundred and fifty-eight beams only makes 257 spaces between 2 beams.Then we had to get up and tell the whole class what we had found out. First we asked them to guess the answer . George was the closest. He guessed 1500 cars. Then we explained what we had done .Our new answer was: 257 spaces x 3 lanes x 2 directions = 1542 cars. Then, Ms. T. told us about a really cool artist named M.C. Escher  who played visual games with space filling and perception and I told the class about some of the ideas that I got from my dad about how the bridge could handle its traffic better. He's a traffic cop.All this was a really fun way to learn math. Thanks Tisha! Here are some more fun capacity problems for you to try if you want to. Ms. T.
