Hi there,
This is a nice activity to improve pronunciation. Follow these steps:
1) Listen to the podcast below.
2) Read aloud and record yourself.
3) Practise as many times as you need.
Open your activity book on page 93 and cut out the cards. Once you finish, you are going to play in pairs. One person thinks about a character and the other must ask questions until guessing who the secret card is.
Here you have a pic to help you:
