    I have attached a file of question #17 that says to "Complete the bar model and explain how to use it to find the unknown part."  In the attached file, you will see the two rectangles--one with a blank (I guess) and the other a shaded square. There's also a line that I think is showing that the two rectangles are connected.  Beneath that is another "blank".

    How should this be shown?  Using braille or tactile graphics?  What is the "blank"?

    Thank you,

    Hi Susie,

    Guidelines and Standards for Tactile Graphics 11.2.3 states that graphics for grades K-3 should be drawn. Draw the bar model and the bracket underneath. Use underscores for the blanks provided for writing answers in the left part of the box model and in the center underneath. The solid square should be done as a tactile square rather than a braille-dot shape symbol at this age as well. Do not draw a rectangle for the large blank workspace.

    Braille on,
