    Hi,

    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,

    Susie
