The brothers are perfect to introduce this concept because they have pretty distinct personalities. First, we made a T chart using each brother. Then we went through a list of words that can be used to describe any character. We decided if each word fit the big brother, the little brother or neither.
Finally, I modeled how I would write about this in our reader response notebooks. We'll practice this a few more times in this guided format, then I'll have them do a character analysis independently during daily 5.
In case you don't use reader response notebooks and would rather have a printable copy, I made these for you to download. You can get it here and here.
