After listing desired behaviors and having friends model correct and incorrect behaviors, we began to practice independently. The first day, we aimed for just 3 minutes of EVERYONE doing the job correctly. It took us 3 tries, but WE DID IT! Since then, we have added one minute each day, so that we are gradually building up our stamina.
Kids who were truly engaged in "Read to Self" hardly even noticed their teacher snapping quick photos of them!
