Guessing games are a standard way to play and practice/learn vocabulary.
Simply generate with the class your vocabulary list. It can be recent vocabulary from your book/lesson/unit.
Then, the teacher describes one thing/place/person on the board and students try to guess. Only one guess / student or team ( or you will have some students just saying a hundred guesses!). Erase or mark out each correct guess and play until all have been guessed.
Finally, let the students write down the vocabulary and do the same in small groups or pairs.
Other variations include snap (where the teacher says a word and students must be the first to “snap/slap” the word) , pictionary (some students draw and others guess the vocab item), charades (students act and other students guess the vocab item).
