This work refers to the topic of bilingual mathematics education. It is focused on monitoring the communicational influences of teacher's and pupil's language, categorization of the disturbing effects and possibilities, how the teacher should prepare for them and how to solve them. A significant role plays the reflection of the teacher, as the results were done on the basis of action research during teaching in England, Germany and the Czech Republic.
