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.  \nKey words: mental computation, preservice primary school teachers, board-games, didactic games, mobile games  \n1. Introduction  \nDeveloping pupils’ number sense is one of the most important goals of teaching Mathematics. Performing written and mental computation are competencies incorporated in number sense. But using written algorithms encourages children to follow different steps without thinking (Maclellan, 2001), while doing mental computation they understand deeper how numbers work (Reys, 1984; Maclellan, 2001) . Mental computation has been seen in two ways: as a basic skill or as a high-order thinking skill (Reys [et. al](et. al), 1995). As a basic skill, mental computation is just applying some learnt algorithms, the only difficulty is to choose the right one based on the numbers from the operation. As a high-order thinking skill, it requires the development of new computation strategies based on the properties of the numbers involved (Reys, Reys, Nohda, & Emori, 1995) . In many cases students try to use the mental images of paper and pencil algorithms for performing mental computation, but these are not efficient (Heirdsfield & Cooper, 2004, Varol & Farran, 2007). Thus McIntosh (2005) suggests that “delaying the introduction of written algorithms is beneficial to students”(p. 4). Hope and Sherrill (1987) highlighted that the unskilled students used mostly standard written methods for mental computation, while the skilled students used a variety of mental strategies.  \nMental computation is useful in the everyday life (Reys et al., 1995), but also contributes to the development of higher order thinking competencies, as creative and independent thinking (Reys, 1984), mathematical reasoning skills (Carvalho & da Ponte, 2013), and number sense (McIntosh et al., 1997, Verschaffel et al., 2007) . Thus the development of mental computation competency is very important. To achieving this goal, the teacher also needs to have good number sense (Whitacre & Nickerson, 2006) .  \n2. Studies on elementary pre-service teachers’ mental computation skills  \nTsao (2004) conducted a research among 155 pre-service elementary school teachers in United States, studying correlation between number sense, attitude towards mathematics, written computation skills, and mental computation skills. The results show that written computation skills, mental computation skills, and some subcategories of the attitude towards mathematics, as mathematics anxiety or  \nconfidence in learning mathematics, are in strong correlation with the achievement in the number sense test.  \nWhitacre and Nickerson (2006) had a study with 13 pre-service elementary school teachers in United States about multiplication strategies with two digit numbers. During the intervention the researchers discussed four interpretation of the multiplication. One of the interpretation which was more emphasized is the rectangle/area approach. This approach of reasoning with models led to a large decrease in using men","cbCaigBMARHR7c4M","https://ap.wps.com/l/cbCaigBMARHR7c4M","pdf",753702,12,"English","# 1. Introduction\n# 2.
