Bar and Circle Graph Activity

So the beginning of the week has been a busy one! We started a group activity where students had to investigate the connections between a bar graph and a circle graph. At first they said that they had nothing in common except for the fact that both gave you information, but in different forms (whole numbers, percentages, etc). By the end, they were able to tell me how to take the bars in a bar graph to make a circle graph (and actually did this on their papers), as well as calculating the frequencies, percentages and central angles. Normally activity days have me totally frayed, but this one was great!!! :)
