Here is a free past simple game to help students practice forming past simple affirmative sentences. Give each group of four a set of time expression cards and a set of verb cards. Students place the time expression cards face down in a pile and deal out the verb cards equally. Players then take it in turns to turn over a time expression card from the pile and make a true past simple affirmative sentence using one of the verbs on their cards and the time expression. If the player constructs a believable past simple sentence, which is agreed on by the other students to be true, the player may discard the verb card. If the other students think the sentence can’t be true, or if the sentence is grammatically incorrect, they challenge the player, and he or she has to keep the verb card. The aim of the game is to be the first player to get rid of all their verb cards. The game is quite easy at first because there is a choice of verbs, but it becomes more challenging to make a meaningful sentence as the game progresses.
