dc.description.abstract Starting from the Swedish curriculum’s goals of a school for all children this study’s main purpose is to contribute to the understanding of how mental number-lines are being described and related to by people with visualized number-forms. The study aims to answer the two questions: - How are the mental number-lines described by people with visualized numberforms and in what way do these descriptions differ from a conventional numberline? - What relations can be found between the visualized number-line and the choice of counting-strategies on number-tasks? The study used a qualitative method in which three participants with visual mental number-lines described their preferred counting-strategies and relation to their mental number-lines in three semi-structured interviews. The data was then analyzed by connecting counting-strategies to the described mental number-lines and by comparing the described mental number-lines to conventional, linear, number-lines. Two of the participants in the study displayed a distinct connection between counting-strategies and number-line-visualization. This was shown by the way they adapted their countingstrategies to fit their personal visualization of the mental number-line. The result highlights the importance of understanding how students visualize their number-lines. For further studies this study suggests further investigations regarding how mental number-line-visualizations hinders students from achieving important steps in their understanding of mathematics. en_US
