This classroom note is focused on the application of inquiry approaches to teaching divisibility in the set of whole numbers. The main attention is devoted to the composition of a sequence of questions implemented within the spreadsheet environment, the solution of which should encourage students to actively learn and discover the divisibility rule for number eleven. This is an extra-curricular topic in Slovakia aimed to be taught in extended Mathematics classes as many of their students encounter it in competitions. An important part of the development of the questions on workbook sheets is the implementation of feedback which provides evaluation of students' solutions and auxiliary instructions for the guidance of learning.
