Abacuses (Abacus, Finger abacus) in teaching mathematic operation in lower primary school classes. Suggestion of worksheets with the use of computer.

In my thesis I am concerned with compiled interactive textbook designed for first-year primary school pupils. This textbook focuses on counting with transfer over 5 and 10 with the use of interactive white board and abacuses. In the introductory part of my work I describe the knowledge pupils have when they start their first school year and I deal with Mathematics at the beginning of the first year, abacuses, interactive white boards, textbook and interactive textbook. The main part applies to interactive textbook manual in which I describe the environment, control and particular examples. I also refer to lessons that have been taught at two primary schools. The conclusion consists of a feed-back obtained from teachers in the form of a questionnaire, my self-assessment, and evaluation of taught lessons and their effect on the basis of worksheets
