Create a Circle Graph
We will collect and graph class data in a circle graph.
First, let’s collect data – raise your hand for your favorite type of food:
› Italian› American› Mexican› Asian
![Page 29: Math journal wk 10](https://reader036.vdocuments.mx/reader036/viewer/2022062319/557e6717d8b42a1e178b4aa5/html5/thumbnails/29.jpg)
Create a Circle Graph
Using this data, let’s design a circle graph
Start with the title: Draw a circle where the graph will be
drawn in. Now, cut the circle into pieces
according to how many people voted for each food compared to the whole class (36 people).

Create a Pictograph
We will collect and graph class data in a pictograph.
First, let’s collect data – raise your hand for your favorite sport:› Soccer› Baseball› Basketball› Football› Other/None
![Page 43: Math journal wk 10](https://reader036.vdocuments.mx/reader036/viewer/2022062319/557e6717d8b42a1e178b4aa5/html5/thumbnails/43.jpg)
Create a Pictograph
Using this data, let’s design a pictograph Start with the title: Now write a key where each ball = 2
students Draw a box where the graph will be
made. Label the left side with the sports. Now, draw a picture for each sport.
Remember, you may need to use half a picture to represent numbers.
