Shelley Lovett from Childcareland demonstrates sand writing as an early childhood learning activity. All you need for this activity is a baking sheet that is approx one inch deep and some sand. Colored sand makes it more fun for the kids. Shelley says the cheapest place she has found colored sand is at Wal-Mart, but it is also available at craft stores and perhaps even at Home Depot or Lowes. You spread a thin layer of the sand onto the baking sheet and try to make it pretty even. For very young children, just let them use their finger to make swirls, and any other shapes they want to. For older children, you can give them a card that has a letter of the alphabet, their name. or a sight word, and have them copy it into the sand.
