How do you stack the chairs in your classroom? On desks? In stacks in a designated area of the room? This year, I am going to have my students stack chairs on their desks, though I haven't done that before. I am getting tired of having them make stacks too high, too low, or shoving chairs toward the stack in a rush. I've always been precise in explaining the procedure, but sometimes kids get in a rush and... forget... or take the lazy route, I guess. How do you introduce the procedure of stacking chairs the first day of school?
