The basic figures skated are typically referred to by numbers, the same as those skated by ice skaters, ranging from simple "circle eights" through "serpentines" (figures using one push for a circle and a half), "paragraphs" (figures using one push for two circles), and "loops" (smaller circles with a teardrop-shaped loop skated at the top of the circle). There is one category of simple figures (111 and 112) that are unique to roller skaters; these are serpentines that begin with a half circle skated on one foot, then change to the other foot, for the next circle, then change back to the other foot for another half circle. Some of the more basic figures are numbered 1, 2, 1B, 5A, 5B, 7A, 7B, 111A, 111B, 112A, and 112B, in which the letter B designates starting on the left foot. These figures are often taught as beginning figures for those just starting. They include simple circle eights, circle eights with three turns, and serpentines. More difficult figures include the use of turns like counters, brackets, and rockers, and they are numbered 19, 21, 22, 26, etc.
