I noticed the following article in Wikipedia. "In the Czech Republic, Teachers' Day (Den učitelů) is a non-official holiday, celebrated on March 28, birthday of Jan Ámos Komenský (Comenius). Children are expected to bring their teachers flowers. Public officials use this day to show appreciation to the profession and reward best teachers." Is this tradition still widely practised in the Czech Republic?
The day's papers usually bring an article or two on the subject but in ordinary everyday situations you won't notice anything special. The thing about children bringing present to their teachers may be true, but mostly only at some high schools, not at elementary ones.
