Have them make nonstandard, oneunit tape measures out of adding machine paper using five different colorpencils. Create, label and discuss the measurements of onewhole; then 1/2 and 2/2 and 0/2; then do the same for fourths, eighths and sixteenths. Label each part below the previous segments on the paper. Using different color pencils will help. Practice measuring a pen, or other item they all have that is shorter than the 1 unit measure they have each time you make a smaller measuring segment. Keep track of each measure on a Tchart! Helps with estimation, too. Have them use their nonstandard ruler as a math bookmark!
If you have an overhead projector or electronic whiteboard, give them practice identifying magnified models of measurements. I don't know if there is a Jeopardy game that would supply that practice, but you could search.
