1. Present Continuous picture differences
Students describe their pictures to each other and try to find differences. These can either be a single picture that is changed with Tippex or Photoshop to have differences in it, or two completely different pictures. If the pictures are completely different and so differences are easier to find, get students to compete with other pairs to find as many as they can in a fixed time period.

2. Present Continous picture similarities
If you have two completely different pictures, it is more challenging for students to find any small similarities between them rather than differences as in the game above, e.g. “A man is standing up”
