1-100 Rules Ok?
Thompson, Ian
Mathematics Teaching, n185 p14-15 Dec 2003
In a recent edition of "Mathematics Teaching" Midge Pasternack argued the case for the use of the 0-99 square with young children rather than the ubiquitous 1-100 square. In this article, the author would like to take the opportunity to mount a defence in favour of the much maligned 1-100 square. His main criticism of the 0-99 square (apart from the linguistic and logical difficulty of having a 100 square that only goes as far as 99) is that it does not support the development of a particularly important concept in number understanding for young learners, namely, the relationship between cardinal and ordinal numbers. If children are going to make sense of number lines to the extent that they become confident with empty number lines they need to understand this relationship. He feels very strongly that the 0-99 square actually prevents children from making this important connection.
