The value of oracy skills can be carried with you your whole life. There are many situations that require you to communicate effectively.
Humans speak 10s of 1000s of words each day. Therefore, you have oracy skills already built up whether you believe it or not.
Do not associate the words oral presentation with "speech". There are many options that you can engage with to complete an oral presentation. You can complete these individually or as part of a group:
Rap or song
Slam poetry
Socratic Dialogue
Debate
Seminar
Demonstration
Explanation
Dramatic monologue
Podcast (this is like a radio show)
You can FILM/VOICE RECORD your oral presentation. However, you must plan and check it with your teacher first :-)
