Here is a set of flashcards which presents Present Simple tense with pictures. There are ten pictures in the set which illustrate positive, negative and question forms in meaningful sentences. The flashcards will help you get the meaning across.
There are two sets of flashcards: with captions or without captions. The set without captions can be used in a revision lesson. The students can be asked to describe the photo which will give an opportunity for them to use present simple tense in a meaningful context.
