Math lesson-outdoors 1(scaling)

We had difficulties figuring out the scale at first and took a very long time to calculate it.We were so frustrated and irritated.We asked Mr. Chiang, but, he did not give us the answer we wanted to help us find the answer.I was more frustrated.We were in a silence for awhile until one of us found out the wrong.We were suppose to find 'cm is to m' but instead, we actually found 'cm is to cm'.In addition,we knew what was the scale we were going to use.We were so relieved.As i was about to draw the map on the paper, Mr. Ciang asked us to line up because his class has finished.I was furious!!!
