According to PBS, one great way to encourage literacy in the home is to have a variety of writing materials available. In our home, we have a cupboard dedicated to kid-friendly craft supplies where they can find multiple kinds of paper, dry erase boards and markers, crayons, pencils, washable markers, paints and paintbrushes and coloring and/or activity books.
I love the suggestion of having a model of all the letters available for young writers that allows them to refer to it if they have trouble remembering letter formations.
The one above will easily work for now until I can find (or make) a better piece to hang on my wall.
