Within ACL 3.2, back and forth movements create the concrete concept of a line after it is visible. The actions rub over the same space, which can be seen as a wide line.
Different objects on different surfaces can create a line:
- The objects can include sticks, crayons, pencils, pens, and brushes.
- The surfaces can include dirt, sand, paper, and walls.
Familiar objects that are bilateral and can be moved back and forth include sanders and rolling pins.
Familiar, one handed objects that can be moved back and forth include paint rollers, wallpaper rollers, scrub brushes, bottle brushes require two hands, squeezing water out of washed clothes, tooth brushes, soap, lotions, dust clothes, and bath sponges.
Using rubber stamps and stamping pads can be set up with a nice back and forth motion between the stamping pad and a piece of paper.
Within ACL 3.2, turning pages, folding, circular motions, sewing, sweeping, propelling a wheelchair, using a rolling pin or a wallpaper roller are additional movement patterns that might be stimulated. The individual's activity history may contain some clues about equivalent actions or the following can be tried. The objects are classified according to the action.
Turning Pages
Looking at the pictures in books, magazines and calendars.
Folding
Linens such as tea towels, hand towels, wash clothes and napkins are a good size.
Bath towels are usually too big.
Stacking is unlikely until ACL 3.4.
Circular Motions
Polishing shoes, drying dishes, dusting furniture and washing table tops are apt to be done with a habitual action for that individual. Most people will probably be unable to vary the back and forth motion within ACL 3.2.
Sewing
The standard size sewing needle and thread is usually too small until ACL 5. The pre-punched sewing cards designed for three to five-year-old children provide an opportunity to use sewing habits that is a pleasure for people who have done a lot of sewing.
Sweeping
Sweeping is usually characterized by the back and forth motion in the vertical plane.
Vacuuming is usually the same motion. The machine does not need to be plugged in because they are only paying attention to the motion.
They are apt to bump into furniture and people that are in the vicinity. A lot of clear space is needed for this activity to be safe.
Propelling Their Wheelchair
Using the rims to propel themselves is possible only when this is a habit they have stored in procedural memory.
The problems of bumping into furniture and people are the same as sweeping. Within ACL 3.2, the safety of other people is not apt to capture their attention.
Rolling a Wallpaper Roller
A wallpaper roller is a new idea that merits further development because it has a natural back and forth motion.
It is, however, a tool in need of a surface. Play dough is suggested.
For something reusable which will last for a few months try this play dough recipe. http://www.bestrecipes.com.au/recipe/Play-Dough-L926.html. The recipe requires salt, flour, cream of tartar and water. You can add food coloring.
If you do not have cooking facilities for this cooked play dough, this recipe also works with boiling hot water. Do not do this with the resident present. The preparation time is fast.
The roller can be used to roll out strips of color and then roll them together. Within ACL 3.2, someone will need to roll and handle the play dough for them, but they can paint it.
When they are done, the play dough can be reused or thrown away. People within ACL 3 are interested in the action and not the project.
