This is a game of dominos. There are 16 words used in business correspondence, either letter or email, and their descriptions written on domino cards which you have to then cut out. The students share out the cards, and try to place them in the correct order. I made this for a one on one lesson, but it can easily be used with more students. My lesson plan would be to introduce the words, and elicit their meaning, play a game of dominos, get the students to use the words in sentences and do a role play of a boss dictating a business letter or email to a secretary, trying to use as many of the words as possible.
