Teaching the 4 skills of language - reading, writing, listening and speaking - is important for CLIL activities. The teacher must consider a student's age when choosing activities since skills develop at different rates. For example, reading activities are not suitable for preschoolers. To improve reading, students can underline unknown words in a text. Developing writing involves summaries and mind maps. Listening and speaking are improved through songs, role-plays and videos. Some activities like watching a documentary with subtitles aid multiple skills.

TEACHING THE 4 SKILLS
As we know, if we want to develop a good clil activity. this activity must improve
the four skills of language:
writing
listening
speaking
reading
But the teacher must be aware of the student's age, because the development
of one skill can be appropriate for one type of students but not for others. For
example, logically reading activities can't be used with preschools kids.
Now, I want to mention some activities in order to improve each skill.
For example, If we want to improve reading skill, we can tell to the students to
read a text and underline the words they do not understand.
Moreover, if we want to develop writing skill we can use summaries or mind
maps.
On the other hand, if we want to improve listening and speaking we might use
activities like songs, role-plays or videos.
There are also, some activities which help us to develop several skills at time as
watching a documentary with subtitles, where we could improve listening,
speaking and reading.
