What has a foot on each side and one in the middle? Measuring mathematicians are to match measurements in column A with equivalent measures in column B in order to solve the riddle! Most of the measurements in column A are written out in words, whereas those in the other are simply a number with a unit. All are in standard units. Once the matching is completed, the letters for each answer are translated into a code that answers the length riddle. This is a cute worksheet that you could give to learners who finish basic skills practice before the rest of the class.
