For the third time this year fast-multiplying contest (Międzyszkolne Mistrzostwa Szybkiego Mnożenia) was organized in Azymut School. The organizer of this event and one of our partners is Mr. Dobromił Błachowiak. Mr. Dobromił’s students who attend mental arithmetic classes took a part in the contest of counting on abacus. We were honored to award the students who had the best results. It was a great opportunity to conduct demonstrational lesson, when kids knew more about history of abacus that we use during our lessons, how to count on it. In the end of lesson those who answered our questions correctly, received a vouchers with the discount on our classes.
