When working with struggling readers, of of the things I found hardest to teach was *when* they needed to stop and think while independently reading. Students who could answer deep questions during read aloud lost all ability to do so when it came to their independent reading -- even when they were ostensibly reading "just right books." I created thinking prompts for certain books, allowing students to "stop and jot," but given them a little direction. This eliminated a lot of the lame post-its like "wow" or "I think Andy is nice," and helped raise reading levels. I liked to start with the first book in the series to then remove the scaffolds slowly as the series developed -- putting blank post-its at critical moments in the second book, then having students read the third book completely independently.
**You can print these on regular sized post-its with a little trial and error.
