Writing is contagious!
Kindergartners can and will write. The most important ingredient in the recipe for writing in kindergarten, especially if the children do not have any previous experience with writing, is the attitude of the teacher. If the teacher pretends that the children will write, they begin to expect that they will. Use language that indicates that you believe the children are already writing, that what they are doing is writing. “Let me see what you wrote.” Yes...a capital at the beginning of your sentence...nice job" “Wow! You wrote that?” "You did a great job using spaces between your words" “What are you thinking of writing about today?” etc.
