Prepare four sets of slips of paper before class. On one of the sets write 10 verbs, on another write the different English language tenses, on another different pronouns, and on the last pile the words, "positive" or "negative." Divide the class into groups of three. Take a slip of paper from each pile and read out what is written on the slips. For example, "go, present simple, his, positive." Ask one group to, within 20 seconds, construct a positive sentence in the present simple tense using the words "go" and "his," for example, "His dog goes outside every day." If the group manages to construct a good sentence award it one point. Take another slip of paper from each pile and read out the words to the next group. Continue in this fashion until you have used all the slips of paper. The group with the most points wins.
Write the word "turnip" horizontally on the board. Divide the class into two teams. Ask one team to provide you with a long word starting with the last letter of this word, "p," such as "personally." Write this vertically on the board. It is now the other team's go to think of a long word starting with the letter, "y," which you will write on the board horizontally. When the board is full, add up all the letters in the horizontal words and award the team that thought of these words the same amount of points. Do the same for the vertical letters. The team with the most points wins.
Draw a large clock on the board. Next to the numeral 1 write the letters, "a" and "b." Next to the numeral 2 write, "c" and "d." Continue writing letters until all the numbers have two or more letters next to them. Divide the class into three groups. Read out a word that the class has recently studied, for example, "Routine." The first letter of the word is "r" and will be next to the number nine. The last letter of this word is the letter, "e" and will be next to the number three. Students use the first letter as the hour hand and the last letter as the minute hand, so "routine" corresponds to the time 9:15. The first team to tell you the correct time gains one point. Continue reading out more words and awarding points for the correct time.
Ask the students to tell you 10 adjectives and write these on the board. Now ask the students to tell you 10 countries and also write these on the board. Divide the class into groups of three or four and ask each group to write 10 sentences comparing the countries using the adjectives. For example, "Russia is colder than England," or "Argentina is more interesting than Bolivia." After 20 minutes, or when most of the groups have finished, ask each group to read its sentences to the class. Award each group one point for each grammatically correct sentence.
