1. Not that kind of bubbles.

2. THE BASIC BUBBLE CHART
Main Argument
Susie’s ribbon is not a hat
Does not cover her head
Does not protect her head
Supporting Argument
Supporting Argument
The bubble in the middle contains your main argument.
Bubbles stemming off of that contain your supporting arguments.

3. Next, you start adding evidence to back up your supporting arguments.
Susie’s ribbon is not a hat
Does not cover her head
Does not protect her head
Would not keep head dry
Not fitted to her head
Does not cover her whole head
Too flimsy
Explain to students that really, two pieces of evidence for each argument is not enough. This is just an example.
Add more evidence . . .
And more evidence . . .
Until you have enough evidence to back up each supporting argument!
