I've been working on a visual "work system." It is based tips from my helper at the TEACCH program, things I've read from Anabelle's blog & a lot of thinking. 

Here is the
first part that I've made:

The idea for this schedule is that:

-Post-its are added, showing the work to be done.

-The post-its are removed as tasks are done/moved on to.

-When they are removed this reveals "done!"

It is a motivating, concrete & visual way to show progress through out the
day! I *REALLY* like getting to remove the post-its. I also like being
able to *SEE* how much work is left until I am done!

The colors & numbers also help with sequencing. So do post-its!

If I write a "to-do list" & it gets in the wrong order, it is hard to fix.
It is frustrating! If I leave out a step in the middle, it is hard to put
it in when I am done.

With post-its, if there is an error, I can simply rearrange them or throw
one out & make a new one. This makes more sense & works as a better visual
for me.

By limiting the number of things to do to 4, it is less overwhelming than a
writing a big list.
