Nuts and Bolts construction box
Screws with flat ends (nothing sharp), bolts, nuts, plastic wire caps, metal strips with holes in it (like these)
Other additional objects:
allen wrench, wrench, pliers, screwdrivers, toy construction vehicles
especially diggers and dump trucks, wooden construction signs, and maybe
even a few big magnets.
Where to get this stuff:
save all the pieces that come with furniture-in-a-box because they
usually include extra screws and a "disposable" allen wrench. I also
accumulated some of this "junk" while my grandmother was moving out of
her home. This is one of the items on my list of things I save.
you don't have a stock pile of nuts and bolts, I'd recommend starting
by calling a local hardware store and asking if they could donate any of
these materials to your school. You never know! You could also put an
ad on the wanted section of Craigs List; I have obtained large
quantities of strange materials like glass jars and egg cartons via CL.
This unit may occur because the class or children are particularly interested in construction. This may be especially pertinent when there is construction occurring close to the school or your home or if a parent visits who is a construction worker.
This may also be a larger part of a vehicles/transportation unit or a How-It's-Made unit
No image yet because I have yet to create this sensory box but I will be doing this soon!
