Relative Frequency, Fractions and Percent Conversion: Choosing Sports

This GeoGebra lesson uses interactive multiple-choice and open-response tasks to demonstrate how a sports-selection dataset is converted into relative frequencies and then expressed in fraction, decimal, and percent forms. Students investigate what share of children selected a given sport (including cases like 16%), explain why making a frequency table is useful, and justify why the sum of all relative frequencies always equals 1. The construction emphasizes core probability & statistics ideas: computing relative frequency, translating between representations, and reasoning about totals. It is built with interactive selection and feedback logic using objects and commands such as SelectedIndex (option indexing), If (correct/incorrect checks), Textfield/InputBox (student answers), and multiple question-flow objects (questions, q1–q5, question) plus navigation buttons (buttonStart, buttonForward, buttonBackward, buttonWeiter, solution buttons). Data and results are organized into table objects (tabel1–tabel4), while selection-related objects (sports, sports2, studentAnswer, studentAnswer2, marginDropdown) store and display outcomes; additional objects like correct, totalAttempts, and buttonLatex support validation and guided presentation. Suitable for grades 5–6 and for classroom practice on introductory statistics, data representation, and percentage reasoning.
