This Tic Tac Toe Choice Board is an activity that teaches students about some of the major events/missions in space exploration history. Some of the events include the Space Race, International Space Station, Mercury, Gemini, and Apollo missions, Challenger and Columbia tragedies, Mir, the Lunar Roving Vehicle, and Mars Science Laboratory. Students will choose to read about three of the events, then will answer questions about each and complete a Venn Diagram comparing/contrasting the three events. The questions are higher order Bloom's questions. Included are the Tic Tac Toe Choice board with space exploration information and a student answer sheet. This was originally designed as an anchor activity based on differentiation activities from LeAnn Nickelsen.
