This 45" wide by 90" wide color coded windows keyboard will be an excellent addition to any technology classroom. Color coded by hand for little ones and by finger for older children and adults.
You can print this on any standard printer and assemble together like a large puzzle.
Disclaimer: Unless your printer has the ability to print to a "bleed" or all the way to the edge of the paper, you will most likely have to trim two sides of the paper before you paste it together. There are a total of 60 pages when printed at full scale. (Not every page is printed on, it just requires this many pages to have the full rectangular poster.)
