Teacher should wrap up the discussion about using literary devices and why they are important in writing. Write a song about Dr. King. Choose some of King's figurative phrases and represent them in painting. Organize a community service project to pass on the message of Dr. King. Interview people who were at the speech and ask them what was so compelling about the speech.
Older students can arrange times to talk to younger students about the speech and what it all means.
After analyzing two of Dr. King's speeches closely and hearing everyone else's presentations, they should be pretty knowledgeable about his message. Have the class plan an all-school assembly.
