If you can spare some time (LOL) you could volunteer to assist the teacher either in the classroom (help with a craft project, decorate a bulletin board) or at home (prepare materials for a project, collate papers). You could decide if it is a one time deal or one hour a week or one day a month, etc. Your daughter could make a card or "coupons" giving the details of you assistance.
Your daughter could make a pencil cup or trinket holder out of an empty glass jar and glue beads, gems, buttons or ribbon to it.
Your daughter could use items you might have around the house to make holiday ornaments - old greeting cards, paint, ribbon, beads, gems, popsicle sticks, pompoms, chenille stems, etc.
If you are making baked good for the holidays you could give the teacher some.
If you do have a little money to spend you could go to a dollar store, buy a container or and fill it with stickers, markers, pens, stationery, etc that she can use in the classroom.
