An exercise for pronunciation - recognizing /æ/ sound in words (the worksheet is based on American pronunciation). Students have to find their way out of the maze, finding words with /æ/ sound.
A good way to finish teaching English vowel sounds (especially /æ/ sound). You can also ask students to make similar mazes by themselves and then give their mazes to other classmates (e.g. in pairs on any vowel sound they want; don't forget to give them dictionaries so that they could check pronunciation:)
