I moved from teaching 3rd grrade to K this year. As I am reading some of the posts about centers, I am noticing that people aren't really introducing them during the first week of school. I was going to have these centers tomorrow for our literacy time (most are for exploration): 1. introducing playdough (make your name then free play), 2. writing center-introducing paper, pencils and clipboards-write name and words around the room 3. This is ME! book (self-portrait) introduce markers 4. books/puzzles-discuss how we use them appropriately. Is this too much to introduce at once? If so, do I just choose one or two? Do I have everyone do it at the same time? What do I do if someone finishes early?
