With one class we can calculate 10 examples in one hour, with the other class I managed to calculate 15 of them. Therefore, it would be good for me to have more examples prepared for those more gifted students who will calculate ten examples in twenty minutes. We counted in this way that the students received pre-printed examples and solved them themselves in a notebook. In a row, the students went to the blackboard.
