Sorting Ourselves

Today during Math we were each given a number that we had to be, since there were 21 of us today that meant our numbers ranged from 0-20. Mr. Donaldson challenged us to sort ourselves into the correct order by ourselves. When we were happy with it he would come along and read out the numbers that we were lined up in. It took a couple of resorts to get everyone into the correct spot but we got there in the end.
