Firstly, this lesson aims at teaching young post-elementary learners the right form of questions. The most frequent error is 'Did he played tennis?' and 'Did she swam fast?' or 'Does she plays tennis?' This game aims at teaching them that in the interrogative form of present simple and past simple they should use the infinitive form of the verb.
The teacher may use the same table form for other tenses, such as the 'be going to' form or present continuous (with a present or future meaning) and adapt the boxes depending on the requirements of each tense. The aim remains the same, i.e., the right way of using the interrogative form.
Secondly, many learners have a problem with the word order. This could be a transfer error from their mother tongue. For example, the sentence 'Paul read a book in his bedroom last week' has a certain word order in English whereas in my learners' mother tongue (Greek), the same sentence can be said in many different ways just by arranging the word order differently. Therefore, when it comes to English, they also say the words in random order as well. In the particular lesson they are taught that they must first state the subject, then the verb stating the action, then the place the action occurred and finally the time of the action.
