Research supports the premise that students learn most quickly when they are provided instruction that requires a variety of creative and critical thinking skills, study techniques, and metacognitive strategies. Each quick, little- or no-prep activity in this packet utilizes these skills and strategies. Students will find missing links, brainstorm lists that match categories, and create new words from existing ones. The critical thinking games and activities can be used as individual assignments or as class tasks, or they can be used as competitions between groups to reinforce skills or concepts.
