•  If the topic is free choice,  choose a subject you feel confident about.
•  Brainstorm the chosen topic for your presentation.
•  Select the main ideas that will be focus of your presentation,  i.e.,  the relevant points that are most likely to interest the audience.
•   Plan the number of slides needed for the presentation.

 2. STRUCTURING:

•   Organise an initial draft with the main  ideas  already  selected,  bearing in mind that  there  should  be  an  Introduction,  a  Development  and  a final Conclusion that form a coherent structure.  
•   Design the slides to be used in the presentation: order of contents, selection of photos, drawings, graphs…

•  Write in simple and clear sentences the contents of the presentation considering the time you will be given for your oral presentation.

•   Prepare  the  necessary  slides (you  can  use applications   such as Powerpoint, Prezi,  Genially or similar): choose  a format and font size that can be easily read by the audience,  and add audiovisual content -not excessive- that will make the presentation more interesting. 

•   Write some supporting notes with basic ideas and/or an outline to remember during the oral presentation. 
•    Prepare all the technological devices (pen-drive, computer, etc.) you will need and, before  the  presentation,  check  that  they  work  properly. Have  supporting  notes available so that you can give the oral presentation without any technology if it fails at the last minute. 

•  Anticipate possible questions you may be asked at the end of the presentation and prepare the answers.  

•   Memorise your  presentation  and  rehearse it orally  as  many  times  as necessary to fit the given time limit.

4.  ORAL PRESENTATION: 

•    It is a good idea to start your presentation with a question or something that will catch the attention or curiosity of your audience.

•    Never  read  instead of speaking from memory (use your supporting notes if necessary).

•  Speak slowly, vocalise and show interest in what you are saying, pointing out your self-confidence.

•  These expressions can be useful for your presentation: 

• To introduce the topic of the presentation: 

• I'm going to talk about...
• The aim of my presentation is to…
• I've divided my presentation into... (three parts)
• First, I'd like to...
• Second, I'll talk about...
• Then, I'll deal with...
• After that, I´ll focus on...
• Finally… 

•   To  introduce each section of the presentation:

• So, let's start with...

• Now let's move on to...

•  To refer to previous or subsequent content:

• I mentioned earlier ...

• I'll say more about this later… 

• To check understanding: 

• Is that clear?

• Are there any questions? 

• To refer to visual material:

• This picture/slide/graph shows...

• If you look at the picture, you can see...

• What is interesting in this slide is... 

• To conclude:

• In conclusion,…

• In summary,…

• To summarize,…

• To conclude,…

• Thank you for your attention.

• Do you have any questions or comments?

• If you have any questions I'd be pleased to answer them/I'll do my best to answer them... 

• Use your body language appropriately: it is important to maintain eye contact with your audience and show naturalness in your movements..

       Remember that following the above steps is the key to a successful oral presentation.
