The document outlines an activity to help students recap and review a previous lesson using collaborative group work. Students are split into groups based on colored craft sticks and work together to explain the key learning outcomes to their peers. Each group is given a balloon with a question about the new topic and must pop their balloon to reveal and discuss the question. Afterwards, groups present their findings to each other and link their knowledge together on paper chains for later review. The activity concludes with a brief memory test to recap what was learned.
