And an Answer Key
I have used it with my students to make note taking a much easier process where they can easily learn the new terms and understand what they look like. It is also easy for me to see that they are understanding because when they add their own picture I can see if they are correct or not and how to fix their misunderstandings. They are really succeeding using this wonderful glossary!
