Abstract: The teaching of fraction is an old and difficult problem in elementary schools. Themethod of comparison was used in teaching verbal problems of fraction in an experimentalclass, and the achievement of the children was compared with that of a matched classwhich was slightly superior. The results showed that the experimental class had caughtup and exceeded the compared class. The comparison method of teaching helps the chil-dren to solve the contradiction between the old and the new knowledge, stimulates theiractive thinking and thus improves their ability of problem solving in arithmetic.
