Adding concrete materials when performing simple operations, helps build number sense to ensure students are relating quantities to symbols (numbers).

Would be a good activity to do in the first week of school to go over what a teachers job is and what the students job is. With younger kids it might be good to come up with a big list and then scale it down so the final list is not so overwhelming.
