The Duxbury Braille file for the Braille Quark Cards should be used to produce the cards used in the Student Activity: Quarks - Making Arrangements. These cards have been made with a boarder around the Quark symbol for each card. A double lined boarder will be found on one edge of each card to indicate the edge that should be nearest the individual using the cards. This eliminates the need to read each symbol in order for the user to line the cards up properly. To open the file, first save the file to the desktop. Then open Duxbury Document folder and drag the file into the folder. It can then be opened like any other Duxbury file. Click to download and open Duxbury Braille file
