Desperate Times Call for "Post-it Notes"

The other day, I ran into a bit of a problem. I had forgotten my very crummy, pathetic dry erase board/visual schedule in the car and my 3-year-old busy body little student needed a visual schedule pretty bad. I looked around, saw these magical things:

Tiny Yellow Blessings

I grabbed three, wrote an activity on each one, and slapped them on the wall. My little guy was pleasantly surprised, pointed to each and said, "Yellow!" Once we finished each activity, I instructed the little guy to grab the note, crumple it up and toss it in the "finished pile" on the table. Have any of you ever resorted to something this simple?

It kind of looked something like this:

Except it said, "K-cards" (Kaufman), "Buddy Bear," (best book series in the world for pre-k age), and "iPad" (My Play Home is my favorite go-to app)

Gotta go with whatever works, right?
