Decimal notation and decade grouping are the basis of traditional elaboration
of arithmetic. In the approach that we follow, this elaboration goes gradually
through the didactical structuring and extending of number blocks. In this
process of block extending, we use sums, applying the principle of permanence of
the meaning of addition. Then, finding decimal notations for such sums is a
purely calculation task, that is reducible to easier and smaller (already
performed) cases. In this paper, the block 1-�100 is constructed as the
extension of the block 1-�20 and its didactical analysis is executed. Due to
pedagogical demands, we suggest the replacement of some arithmetic rules by
their ``narrative'' substitutes that also have to be meaning-based.
