2 days ago I watched this video on Facebook. Today the expert (GCSE Teacher, PET Xi class) showed this in the class I was supporting. While students were watching the video she was calling out describing sentences using sensory language (what they were actually seeing). This technique aimed at helping students connect what they see with what they hear, that is create mental images. Then they had to write their own sentences.
You can have a look at this helpful guide. It is a chapter on the descriptive paragraph!!
