I enjoyed your presentation. I am really glad you chose to talk about comments. They can be a real useful way to give peopel feedback. If you highlight a specific block of text and then comment, that comment will be attached to that text. Why did you choose Google Presentation and do you think it is a useful tool for in school and out was something that I would love to hear about. Feel free to add this to your presentation if you want to improve your learning mark. Let me know via email if you do! Thanks for sharing!
