A bar graph uses rectangular shapes, horizontally or vertically, to represent the number of items in a category.
A pie chart will divide a circle to represent the number of items in a category.
There is an easy way to turn a bar graph into pie chart by cutting the bars off the graph and taping them together to create a circle. Use the circle to draw your pie chart and color code it exactly as the bar graph is colored. This is a simple and useful tool to show students that they represent the same statistic just displayed differently.
Humor is always a great way to make math more exciting for students and this short clip is great! It is also great to compare the two: bar graphs and pie charts, and see how they can relate. Thanks for posting this!
