These are flowers with stems that have letters on them. You duct tape them to some dowels and stick the dowels into florist foam in a bucket (and it works to use rice, play doh, or beans also) so that the flowers are growing up out of the bucket. You then can have the kids clip matching clothespins onto the right letter. You can paint the clothespins green and write the matching letter on them so that it is like clipping on the flower leaves. You can also have the kids write a word for each letter that they clipped onto the flower.
