Have you ever done a task analysis? A task analysis is where you really watch your child attempt a set task, and target the problem areas. Then you break that task down into small segments that fit their needs.
Here's an example:
Brush Your Teeth!
Take out your tooth brush
Rinse it off
Open the toothpaste
Apply just a little on your tooth brush
Brush the front of your top teeth
Brush the front of your bottom teeth
Brush the tips of your top teeth
Brush the tips of your bottom teeth
Brush where you chew
Brush the back of your top teeth
Brush the back of your bottom teeth
These are VERY important to daily visual schedules !
