(This is a sideways J. I didn't have the energy to figure out how to rotate the photo.)
S has just started to show an interest in writing letters and so we began with making letters in a tray of sand (I used a small box lid). What I love about this is that he can use his finger instead of a writing instrument and it's very tactile, but it's a little too "open ended" for him right now. He needs more of a guide...
(Again, too tired to rotate this.)That's when I saw this idea and wanted to give it a try. I bought the same border from Dollar Tree, cut it up, and laminated each letter. You can use dry or wet erase markers. I love it because there is room for error and it gives S a guide, but the dry erase markers are a little cumbersome for him still.
I think I might back it up a bit and try having him trace puffy paint letters with his finger first because they are so tactile.
When his writing skills are more developed I plan to start using a highlighter to write letters/numbers and draw shapes and have him trace over my highlighter with a pencil, but he needs more room for error for now.
