You could do an entire lesson on "Tolerance"
-What is it? (dictionary meaning, personal meaning)
-What does the word mean to each student?
-With whom and how can we be tolerant?
-Where have they seen it recently?
-Where have they seen intolerance?
-How have tolerance and intolerance effected those involved?
-What do individual students do to be tolerant?
-What are some things that people think are being tolerant, but are actually racist or intolerant?
Activity: for each letter of the word "tolerance" find other words (or pictures) that describe it.
For example: under "T" you could have the word "talking" and show students talking about differences in their cultures or talking about things concerning tolerance that bother them
