You could give them all your snip its or scraps & have them glue them on a jar for a pencil or crayon holder. I have done this with small children & they loved doing them. I let them use mod podge to glue the peaces on & then let them paint two layers of mod podge over the fabric. Letting each layer dry good before adding the second of course. You could also give them lots of different sizes of squares, rectangle, triangles & let them glue them to paper making there own block. You can then later sew their blocks for them. If they done several blocks, you could put them into a small quilt of their own.
