I use this as a gifted and talented tool as well as a fast finisher project. Every week we assign a new “researcher”. Every time a student completes something or just has a question during center time they can put it in the research box. The researcher is responsible for finding the answer and answers back in complete sentences. We have learned some interesting things from this! My students can’t wait until they are the researcher. We read the responses once a week on Fridays.
