Juniors Experiment with Numbers

Extract

We give here an account of a series of lessons in which a class of Juniors carried out some simple experiments with numbers. In these experiments the numbers, expressed in the familiar Hindu-Arabic notation, were subjected to certain sequences of operations from which there resulted fairly obvious digital patterns—reversals, interchanges, transpositions, rhythms and so on. These patterns were the focal points to which the attention of the class was directed.
