摘要：Mental calculation is an important competence in everyday life, and it is essential
especially for a future primary school teacher. In this research the efficacy of different games, as
didactic games, board-games, and mobile games for developing mental calculation skills were
studied. The results shows that didactic games and board-games were efficient in developing mental
calculation skills when the operations are presented visually, and the didactic games and mobile
games, when the operations are presented orally. In case of visually presented operations there is no
statistically significant difference between the effects of the three type of games. In case of orally
presented operation the didactic games had a significantly higher effect on developing mental
calculation skills as the other two type of games.
