Lack of many mathematics skills caused difficulties in solving problem. Students are required to apply and integrate
many mathematical concepts and skills during the process of making decision and problem-solving. Garderen
(2006) stated deficiency in visual-spatial skill might cause difficulty in differentiating, relating and organizing
informations meaningfully. However, the lacked of mathematics skills among students are varied (Hill 2008;
Kaufman 2008; Berch & Mazzocco 2007; Garderen 2006; Osmon et al. 2006; Garnett 1998; Nathan et al. 2002).
This study looked into five types of mathematics skills.
