Critical Thinking Flip Centers strengthen critical thinking skills by creating opportunities for students to think about everyday objects in new ways! As they answer questions based on Bloom's Taxonomy, students progress though the levels of knowledge, comprehension, application, analysis, synthesis and evaluation. Centers can be used individually or in small groups and include removable answer keys. Each center features and easel-backed stand that allows it to remain upright while students flip pages to work from front to back. Questions can be completed using basic classroom supplies. 28 pp. Grades 3 . Measure 5? x 6".
