How do I complete our wiki assignment?

Create a digital copy of your page first, then past it on the wiki page. If you are using another document (graph image, digital drawing) please don't make us download it to see it, upload the image to the page instead.

There are two purposes for the wiki. One, to give all students experience and practice using technology to display their ideas. Second, to assist those not present in class to give them a sense and concrete examples of what has happened in class on the day of the lesson. Keep these goals in mind as you check your work.Your page should include all of the following information, and anything else that you would like to improve the appearance of your page. Notes should summarize the class. Be sure to include the following:
 * Today's Date
 * Your Initials
 * Big Idea:
 * Essential Question:
 * Notes from Class:
 * Any new vocabulary and definition(s)
 * Any examples from the white board
 * Methods and strategies discussed in class
 * Your own questions
 * Problem set with **copied questions (in bold text)** and complete answers (in normal text), be sure to number your work. Show your work/thinking and include __at least one__ uploaded diagram or image.
