Painting with Water on a Chalkboard - Great idea! Also suggested by "Handwriting without Tears" program. If you do not have chalkboards, get the chalkboard paint from Home Depot or Lowes, or Chalkboard fabric. Kids will love painting with water. Practice letter formation, recognition, and grip and fine-motor skills! from http://lifeatthezoo.com/2012/06/abc-for-preschoolers
sight word target practice (plus little kid version)- great way to teach reading skills/new vocabulary to kinesthetic learners- could modify this idea to include foreign language words, letters, numbers, "build" a word/sentence, shapes, etc.
