Predictions are important for reading because it gives the reader purpose and helps them monitor their comprehension. I made this video to help start a discussion about what a prediction is. These images are easy for most students to access and understand, so it is a good way to use previous background knowledge to introduce new skills.
The video offers question prompts and when to pause. Basically, stop the video at those parts and have a conversation with the class. I start with small groups and then report out to large groups.
