[whatever]

HUGE difference.

If you do not, you want a printer and enough ink cartridges--even color if you can.

Then, everything to make your own curriculum falls in line next.

Lamination sheets and a personal laminator
Velcro strips and dots
command hooks
folders/binders of various thicknesses
plastic bins/shoeboxes
Stuff to fill those boxes with tasks and activities--manipulatives of every shape and size
Sharpies of all colors
dry erase markers
fidgets
clipboards
file boxes
good scissors
Those Sterlite drawer things

For organization, I color code as much as I can. My students are color-coded. My subjects are color-coded. I don't worry if those colors overlap some.

With the stuff above, I can make about anything else. Even in the HS SpEd classes, I try to make as much as possible hands-on, especially with the lower functioning students.

Sometimes worksheets are a necessary evil. I can use google for that.
