Since the girls were so into their graphs, I decided to have us just go with it and explore graphs even more.
My goal was to expose the girls to different kinds of graphs since they were interested and to help them see that in math you can say the same thing in many different ways.
As I mentioned before, we graphed what type of pizza our family and friends like to eat.
We then turned that pictagraph into one using slices of pizza to show how many people prefer which kinds.
To help you create your own pizza graph, here are the images I used:
Following that we also colored in a bar graph similar to the pictagraph with pizza slices. The girls were able to see that each graph made the same shape and gave the same basic information even though they looked a little different.
Of course we had to make pie graph when talking about pizza. I cut large pizza images into slices and we assembled the slices to make a pizza pie graph showing the different preferences with pizza slices. To make the slices all fit together, I actually used powerpoint to “slice” the different kinds of pizza into the same size slices (We surveyed 28 people so each pizza–cheese, pepperoni, supreme, etc–was divided into 28 equal sections.)
We didn’t do quite as much with the graph we made about what people loved as a baby.
We translated our big graph with people’s pictures into a smaller pictagraph using heart shapes. I tried to get the girls to make their graph horizontally but they were not going for that. I did make sheets of hearts, both blank to be colored (like we used) as well as hearts of various colors to use.
I probably wouldn’t have introduced so much graphing so early but since the girls were excited, I was happy to follow their passions. And I think the idea that the same idea can be expressed in different ways is a great take away that will help them as they move forward in math.
