Use music games. Music is a fabulous tool to consolidate existing vocabulary knowledge and to add more words to the knowledge base of those learning English. Play the class a song with simple English lyrics and then ask the students to complete some worksheets afterwards, which could ask questions about the meaning of certain words or the song as a whole. Alternatively, you could hand slips of paper with words on them to groups of students and ask them to form the words into their own song titles that make sense.
Play charades. A game of charades can help the whole group practice English vocabulary. Divide the class into two teams and give each team a few minutes to write down the titles of films and books in English on pieces of paper. Each team should place their pieces of paper into a separate bowl. Ask individuals in each team to take it in turns to pick out a piece of paper from the other team's bowl and act out the film or book written on it. Encourage everyone in that person's team to guess in English what is being mimed.
Play the 'find someone who' game. This game encourages students to interact with each other to find the answers to certain questions. Hand out a piece of paper with a number of questions on it. Examples are "find someone who has a pet" or "find someone who does not like Italian food." Then encourage the students to mingle with each other to find out the answers to those questions in English. This game helps students to practice conversation, vocabulary and writing. This works best in smaller groups of up to 10 people.
Do a "sentence race." Divide the group into two equal teams and hand each team small pieces of paper, each with a word on it. Each team will have exactly the same words, and there should be enough pieces of paper so each student has one word. Call out one of the words. The student from each team who received that word must run up to the blackboard to write a sentence using that word. The first person to finish a correct sentence earns a point for their team. This is a good game to practice vocabulary and sentence construction.
Play "animals for a day." Not everyone likes to act or be noisy in front of a class and this game allows students some time to think before sharing with the class. Ask everyone to think about which animal they would choose to be for a day. Then give them ten minutes to write a few sentences about how it feels and what they are doing. Ask each person to share this with the class once finished. Students will helps others learn the vocabulary they know and you can discuss whether or not their sentence construction is correct.
