Along with the original program of "The Letter People", its mathematics-equivalent program "The Number People" was also created circa 1977. The Number People are referred to as numerical "friends" or "cousins" of the Letter People and were created to help children learn not only about numbers, their sounds and how many there are in each number, but also symbols, mathematics, time, addition, and measurement. They range from numbers 1-9, with odd numbers consisting of males and even numbers consisting of females. Each Number Person carries a number of objects to teach children how many there are to represent the number (such as Mister 1 having "only one of everything: a one-legged table, a one-legged chair, one microscope, one test tube and one clock with one hand"), and also represents the job they employ: Mister 1 as a scientist, Miss 2 as a doctor, Mister 3 as a pilot, Miss 4 as a construction worker, Mister 5 as a sports player (similar to Mister K), Miss 6 as a shape stacker, Mister 7 as an ice cream salesman, Miss 8 as a photographer, and Mister 9 as a magician.
