Here's the rest of those great "tips for teachers" from the SPD Network site:

Children Who Need Sensory Input to Stay on Task
Some children are "sensory seekers" and become more organized and attend better to a task if they receive periodic movement input. Some ideas:
-- Allow a child to sit on a baffled camping pillow filled with a small amount of air. This allows for movement without leaving the desk.
-- Suggest five minutes of swinging or climbing during recess, prior to coming back to class.
Some classrooms actually have a swing or mini-tramp at the back of the classroom for periodic vestibular breaks.
-- Suggest some rhythmical, sustained movement (e.g., marching, washing desks, or bouncing), which can be organizing to the central nervous system.
-- Ask the child to erase the blackboard or run notes to other teachers, to allow him to get some extra movement.
-- Use a rocking chair in the classroom for periodic "pick-me-ups."
-- Never discipline a "sensory seeker" by taking away recess privileges or physical education — you will intensify the random movements, fidgeting, and outbursts

.
Not to mention that children with anxiety disorders – such as OCD, PTSD or Tourettes are made more anxious by punishments as well – so disciplining a child for outbursts or movements by insisting they stop those movements just builds that anxiety higher and higher! Parents of children with SPD should really have this last tip written into their child’s IEP, because losing recess privileges seems to be especially common.

Some children also need extra sensory input to their mouths and hands in order to organize their behavior, such as:
-- Drinking from water bottles kept at desk (send them home weekly to be washed).
-- Chewing on a straw, a coffee stir stick, or rubber tubing placed on the end of a pencil.
-- Fiddling with something in their hands (keep a bucket or fanny pack of "squeezies" handy; a "squeezie" is a small object that is soft and can fit in the hand, such as a balloon filled with flour, a soft ball, a dog toy, or a koosh ball).
-- Hanging by the arms on the monkey bars for 20-30 seconds at a time.
-- Pushing/carrying heavy objects (e.g., carrying books, moving desks, or "pushing" against walls).
-- Carrying a backpack weighted with books or bags of dried beans (this should be worn for only 15-20 minutes at a time, with an hour or two between wearings).

LuLu has a “bumpy ball” – official OT name is Gertie ball – that she loves to fiddle with, especially if anxiety or boredom builds. So much better than the alternative of picking her cuticles or any scabs she has (YUCK!) Haven’t tried the weighted objects yet, but could see where that would be helpful as well.
