As a mentor, one of the things I ensure I do is be honest with the kids about what I DON’T know. They need to understand that a teacher is not necessarily a know-it-all person. To cite an example, during a vocabulary building game if it so happens that I am unsure of the existence of a certain word, I openly tell them that I need to check. This makes them also feel comfortable about sharing what they don’t know. They don’t feel any embarrassment about not knowing a certain thing.
