We enhanced the water tray by adding a washing line. As well as wringing the clothes of water and in turn developing gross motor skills they also developed their fine motor skills by squeezing open the pegs! Also lots of fun!
I'm all over this Moon Dust sensory tray idea -- not just for making letters, but designs of any sort. Excellent activity for Moon Day & beyond. // Mark making in moon dust - a sensory tray for early learning pre-writing
