Some things I hope to change:
1. Make it more interactive: getting up or doing things together so I don't talk most of the time.
2. Make sure I have enough pencils for everyone. (I ran out.)
All in all, I felt it went well, and everyone seemed to have a good time. Perhaps I can do this presentation again at another school sometime. Any presentation tips you'd like to share? Let me know in the comments! Enjoy the slide show.
