What Curriculum Do You Use and Why?

What curriculum do you use? Why do you use it? What do you like the most about it? What might you like to see be different with it? Throughout the month of April I will be focusing on curriculum. While I can sit down with a curriculum, read through it and give you a review of it's strengths and challenges, actually using it is the way to know the most about a particular curriculum line. 

I have actually used a number of curriculum lines throughout the years; but not all of them. So, I'm asking you to please get involved with this year's Curriculum reviews. As I post the reviews, please comment if you have used the curriculum in the review. Please tell us why you chose it, what you like the most about it and if there is anything you might like to see be different with it. I would sincerely appreciate your honest comments, but please try to keep your comments positive as possible, or at least kind, remembering if a curriculum was not a good "fit" for you, it does not mean it will not be a good "fit" for someone else.

My reviews focus on the features of a curriculum, the type of curriculum and it's strengths. Your comments can truly serve to help those of us who are trying to find our best curriculum fit by hearing first-hand from people who are using the curriculum; please share your perspective! Thank you!
