The decoding boards, which are your basic dry erase boards, help students visually see what their brains do as they read which is looking for blends, digraphs, long/short vowels etc. Rather than simply reading off the board, I have students write the words we practice in phonics and write the diacritical marks that support and show them how to decode words along the way that then support their reading.
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.
My school's Blended Learning Coordinator was hired to provide blended learning support. He is provided with our schedules so that he can monitor usage and provide support if needed. While this does not mean that he is present in the classroom daily throughout the use of BL, he does try to walk around and address immediate concerns that students may need addressed. If immediate action is required a quick text can be sent to him and he'll make his way towards the classroom as well.
One of my goals as a first grade teacher is to develop independent learners that can problem solve or decide when it is time to request assistance from others. Self-reliance is a need that many parents talk to me about during conferences and as a result, I've turned to two different strategies in the classroom that allow students to continue their work while informing me of their comfort level of the task. These strategies are known as self monitoring tools that help me to prioritize which students I need to assist first.
