This was our final peer taught lesson on math integration. For this lesson we talked about the number Pi and it's history. We were given a small piece of paper with the number Pi on it, 3.1459... Then we got a piece of graph paper and for each number of Pi, that was the number of boxes we colored in for each column. After we had a Pi skyline we used watercolor paints and crayons to paint our background. As an extension activity students create a bar graph for the frequency of the numbers in Pi. They could have the numbers on a sheet of paper, like we did for our skyline, and create a bar graph that showed the number of times each number appeared in Pi. As a class we could then talk about which number is more common and less common in Pi.
