A colleague of mine gave me this advice a few years ago and it has helped me so much with keeping strategy instruction focused and short. Think - How, When and Why? Explicitly teach students the strategy by showing them how to use the strategy, telling them when you use the strategy, and why you use the strategy. For example: "Today we are going to learn how to check for understanding. We check for understanding by stopping at the end of every page or two and asking ourselves Who is in the story? and What just happened? We do this to make sure we understand who and what we just read about because understanding what we read is important! I will model for you how to stop and check for understanding as we read this picture book. Then you will try it with a partner." She also suggested practicing in front of a mirror with a timer! Worked like a charm!
