Functional Number Line for Students with CVI

This number line is adapted for students with CVI, but can also be used with students with low vision or those who use braille.

I made this number line for one of my students with a cortical visual impairment (CVI).  He is learning about number lines in his kindergarten class and we needed a more functional one that would be not only easy to visually fixate on, but also to manipulate.

  1. cut pieces of black display boardCut display board into a strip. Mine was about 6 x 24 inches.  Use a pencil to draw your straight line, then using scissors, a box cutter or an exacto knife, cut down one side of the board along the penciled line.  Fold board along cut,then using cutting tool, cut along the other side.
  2. Using your ruler and pencil, draw a line straight down the middle long ways.  
  3. Measure out evenly your notches.  Mine were about 4 inches apart.
  4. Using your graphic art tape, tape along your penciled lines.  Depending on the thickness of your graphic art tape, you may need to tape over twice for desired boldness.
  5. Either draw or glue your number below each notch.
  6. Use your black velcro to place a piece above each notch.
  7. Use opposite side velcro piece on your chose object.

You can adapt this to your student’s preferred color.  It will also work for a low vision student and braille student.  For low vision, make sure you use the contrast colors that work best for that specific student and for a braille student, ensure the lines are tactile and incorporate the braille numbers below.
