Three educational games that teach students of English the use of prepositions.
PrepTris: English sentences drop on the game screen like in the cult game Tetris; student must pick the prepositions out of the sentence and click on them. If the student clicked on the correct word(s), the sentence disappears when it reaches the bottom of the game screen.
Conveyor belt: Animated gears turn and move a conveyor belt which presents English sentences with the prepositions missing. There are six correct preposition options to put in the square under the belt. The student must choose the correct as quickly as possible because scores are calculated based on the time spent;
Flash cards: List of prepositions for each alphabet letter in the form of flash cards; Clicking on the card with a preposition turns the card over and shows examples of how this preposition is used.
