Saved by the Bell is a throwback to the old sitcom of my days. During guided reading I use a bell as a means for non-verbal student management, particularly with noise level. One ring of the bell indicates a warning to all that the room is getting loud. Two bells indicates that individuals who I spot are still not keeping their noise level down will run the risk of changing a behavior star. The expectations were set as a class and therefore students know they will be held accountable.
The quick search feature can be a great resource for students. The quick search poster can easily be made to list the topics you want students to search for. While there are book lists that can be created in programs such as MyOn, having students use the search feature gives students some flexibility in what they read while staying on topic.
Flash Fluency is a strategy I use during guided reading sessions to make immediate adjustments to my instruction, based on my students' needs. To gather the information I need, I give a reading fluency check to one student from the group using a current or cold read text. The student reads for one minute while I keep track of miscues and make observations. It is followed by a quick comprehension check. Once this is completed, I address the student's needs immediately with the entire small group. Since my reading groups are homogenous, one student's needs are generally reflective of the needs of the other students in the group.
