I found pie charts and dot plot graphs to be very useful. One of the lessons my instructor gave was using graphs and how important they are to show an amount broken into parts of percentages. Pie charts are broken into different sectors, and each visually represents an item in a data set to match the amount of the item as a percentage or fraction of the total data set.
In class, we did a lesson that dealt with frequencies of M&M's. This lesson gave me a better understanding that a dot plot helps create a pie chart with a more accurate percentage of what the data will be divided into within the sectors.
Cameron,
ReplyDeleteI really enjoyed the activity making the pie chart out of the bars of a bar graph. It would be really useful to help students understand how to construct a pie chart. At first, I didn't understand how we could use the bars to make a pie chart (because a pie chart is obviously a circle). So it is also important to make sure that the instructions are clear for the students to understand.
