I have to spend part of a class teaching HTML to a group of high school students. They are all beginners. The class is short that day, and I will be teaching them things such as:
-How to use a text editor and make the page show up
-Page structure
-What tags and attributes are, opening and closing tags
-Learn about paragraphs(<p>) and headings (<h1>-<h6>)
-'style' attribute values and how to use it
-Other basic but useful tags
-Some basic attributes such as align, style, etc.
-Line breaks and page breaks

The lesson shouldn't take too long. I need suggestions for an activity that the students could do for the part of the class that I'm not teaching, and possible homework. It doesn't need to be a huge assignment, just a little thing that is good for practice.

Also, if you have any other suggestions for my lesson, please add them
Thanks!
