1.1 Counting English: one, two, three, four, five, six,
seven, eight, nine, ten Crow: hawáte,
núpe, dáwi, cope, tsexó, akáwa, sá'pua, núpu'pi, á'pie,
pireké Dutch: een, twee, drie, vier,
vijf, zes, zeven, acht, negen, tien Cantonese: yat, yih, saam, sei, ngh, luhk, chat, baat, gáu, sahp Eager to engage the world around them, young children are born explorers … observing, naming, describing, manipulating, and counting the objects in their world. For them, learning to count is as natural as play. Counting also serves as an informal introduction to the set of whole numbers, represented here as the infinite set {0, 1, 2, 3, 4, 5, 6 …}.
There is more at stake when naming numbers than sound and rhythm, however. In some languages, the naming conventions lead naturally to important mathematical insights involving the structure of the number system. In other languages, naming conventions tend to obscure important relationships. Unfortunately, the naming conventions used in most European languages, including English, fall into the second category. A brief review of English language counting conventions will illustrate the point.
Table 1.1: Base Ten Counting Read across any row in Table 1.1 from left to right, other than the first. In each case, the numbers in the “teens” column are named using a different method that that used in the other columns. This may seem a minor inconvenience to you, but to young learners, this inconsistency poses an obstacle that, all too often, obscures the structure of our system of numeration. For instance, most preschools train children to count from one to twenty. Upon entering kindergarten and/or first grade, children continue to focus their attention on counting, reading, and writing activities involving small numbers. Unless their teachers make a sustained, conscious effort to teach them otherwise, children are unlikely to recognize or understand the most important concept in primary grades mathematics, place value, and its role in our base ten numeration system. For many students, the consequences of this failure are far-reaching and significant. How much easier things would have been if the numbers 11-19 had been named something like tenty one, tenty two, tenty three, and so on. Interestingly, many Asian and languages do not share this failing … and the children who grow up speaking those languages have fewer mathematical difficulties related to base ten numeration.
