GANAG is an acronym for daily lesson planning created by Jane E. Pollock. This slip helps engage students with the objective. It helps you as the teacher start and end the lesson with the objective for the day. Students write down the objective or key understanding for the lesson. They rank themselves on how much they think they already know about the objective before the lesson starts (access prior knowledge). Students rank themselves again at the end of the lesson. This is a good quick formative assessment. Students can quickly let you know if they feel like they learned anything about the objective after the lesson.
