We are using The Reading Lesson and Singapore math, and are really loving both!
My little gal is really picking up reading well with TRL and we love the ease of use. (My oldest used Saxon and my husband was taught with Abeka, so I'm quite familiar with both from our experience and my mother-in-law right up the road. Both of those have a LOT more drill, and take a bigger time committment in our day. TRL is getting the job done well for us...and we're enjoying it, so I say that's success!

) Allison, my 5 yo, also LOVES to write, so I picked up a couple of Explode the Code books for her to add writing to her phonics learning. She thinks they're great fun, but I'm guessing that her brother may not when he gets there, so we won't add them.
We switched to SM this year from Saxon. It does a wonderful job of teaching math!!!

Grant has been challenged to really think, and he understands what he's doing. Math is a strong point for him, and I love to see the wheels turning rather than have him sloppily going through the motions.

I am a math-lover, and I highly reccommend using Singapore. It guides the kids along to understand why they're doing math the way they are rather than just memorizing a series of steps. It also doesn't throw our day out of balance by requiring a huge chunk of time to do daily.
