Pronunciation of the integers with full use of the place value system

Colignatus, Thomas

Kids in kindergarten and Grade 1 live in a world of sounds so that the pronunciation of numbers is important. When they are learning to read and write, the co-ordination of (i) sounds, (ii) numerals and (iii) written words is important. We already have the place value system fully in the numerals but not yet in pronunciation and written words. The following provides for this. The definition should become an ISO standard, though the notebook with package is quite simple because of the nature of the issue. The notebook with package provides an implementation and transliteration for English, German, French, Dutch and Danish, while other languages might employ Mathematica's IntegerName and WordTranslation without transliteration. Four levels in the curriculum are recognised for which routines are provided: (1) sounds, codified by words, (2) learning the numerals, (3) advanced: numerals in blocks of three digits, such that 123456 = {1 hundred, 2 ten, 3} thousand & {4 hundred, 5 ten, 6}, with the comma pronounced as "&" too, and (4) accomplished: 123 thousand 456 pronounced in above place value manner. The traditional pronunciation has level -4.

The package is in the initialisation cell in the notebook. See the PDF at https://zenodo.org/record/1244063. See there also for version history. (An earlier version of this notebook with package is also available at: http://community.wolfram.com/web/community/groups/-/m/t/1334793 )
