Write a story or description about what you can see in the picture. Who is the dolphin? Where did it come from? You could change the girl for yourself and make you the main character in your story. What sea are they in or is it a pool? Where is the dolphin's family? Are there any other animals in the water?
You could write a letter to someone explaining what you are doing on a holiday. Try and use the soundmat on the phonics page to support your spelling. Remember your capital letters, full stops and finger spaces. Can you include the conjunctions 'and', or 'because' in your sentences?
