This activity (detailed lesson plan included) was structured around David Adler's book "Enemies of Slavery," but it's easily adjusted/modified for any classroom textbook/reading on the abolitionist movement.
Students read/research about eight different abolitionists-
--Harriet Beecher Stowe
--Isabel Sojourner Truth
--William Lloyd Garrison
Students are tasked to identify birth/death years of each person, their race, their major accomplishments, as well as answer an open-ended critical thinking question about each person.
Included in this activity:
-- Fill-in worksheet
--Detailed lesson plan
--Corresponding homework assignment - a 1/2 sheet writing prompt asking students to reflect on lesson and give their opinion with evidence: "Who was taking a greater risk: An African-American abolitionist or Caucasian abolitionist?"
