I use it for math for all of my kids and it's going really well. My two oldest had been doing TT and just really were floundering. Especially in the area of fractions. I think CLE teaches fractions, especially factoring and all that really well. I am sold on their Phonics program. I went through 3 different phonics programs with my middle DD in kinder and nothing worked. Finally, in first grade we tried CLE, since it is designed for first graders and she learned to read quickly and is an avid reader now a year later. I like the LA a lot, too. One thing I really like is that the kids can do it mostly independently. It is straightforward and easy to understand.
