This is a two-page Word document in open notes format with the KEY. I like to use open notes when introducing a great deal of information - this avoids the students having to take copious notes by hand. I give each student a copy of the open notes, then project the same copy onto a screen such as a Promethean board. I use the teacher KEY to fill in the blanks while the students are filling in the blanks on their own copy. However, a projector is not necessary; but it's usually the most effective way to deliver this type of information.
Open notes are also a good way to begin a class discussion and utilize questioning techniques.
I usually have a graded assignment to follow up the open notes, and there is one in my store titled "Joints and Skeletal Disorders Open Notes Worksheet with KEY" for purchase under separate cover.
