We have been working on sorting for the last three weeks. I start our sorting unit out with shapes. It's the easiest thing for my students to sort. These pictures show how two of my students sorted their shapes: by color and by shape. Other things I do for sorting include buttons. Who has read "My Button Box"? It's a great book. You read it to the kids and then give them a handful of buttons to sort. This is much more difficult for them but so great!
