Pros:
Great teacher's manual -- very thorough with clear explanations
Strong phonics base, but also gently covers words that "don't follow the rules" -- I was hesitant about these, but it makes sense
Gentle and child-friendly, yet not "fluff"
The lightunits are nice -- my kids are always excited to finish one and start the next
Have you seen the examples on the website? If you want to see more, it would be very inexpensive to order one lightunit to hold and check out. :)
I could list more, but I'm typing and eating dinner at the same time. ;)
I can't really think of anything I don't like about the program. We use CLE for reading, math, and LA, and have for almost 2 years. We love it! I am not looking to change publishers in any of those subjects...I feel very secure that using CLE each year will assure my kiddos a solid education in the "basic" subjects. I save the "fun" stuff for science, history, electives, etc. I'm not tempted by "the latest" new curriculums that I see because I am so pleased at what we already have going. That's a good feeling. :D
Let me know if you have any other specific questions, and I'll be happy to try to help!
