I’ve noticed that my students have many problems producing sibilant sounds, that is why I’ve decided to encourage them to practise these sounds in class and at home.
To help them with this task, I’ve created this slideshow presentation. It can be used for simple practise, or as a game with students organised in teams.
If you like the presentation, you can download it directly from Slideshare. If you want to practise more sibilant sounds, you can visit the post Pronunciation of the initial /s/, where some sentences including this sound are listed.
