This study aimed to discover the numerical ability of students SD the high-ability in solving mathematicalproblems This study used a qualitative method. The subject of this study were one students of class II-B SDI Sunan Ampel II Trosobo with a numerical ability test. The instruments used to collect data were in the form ofmathematical abilities tests, numeracy ability tests, and interview sheets. Based on the results of the numericalability test, it showed, The high-ability subjects were able and correct in using a variety of numbers or symbolsassociated with basic mathematics to solve problems in various contexts of daily life; were able to analyzeinformation displayed in various forms (charts, tables, charts, diagrams and so on); and were able to interpret the results of the analysis to predict and make good decisions.
