I really like that Singapore math does teach my kids the "why" behind what they're doing in math. We love the fun hands-on activities that Carrie has planned in the guide!

My other favorite thing about it is that we're accomplishing math in a timely manner daily. For my oldest, it takes 20-30 min per day (usually closer to 20) and less than that with Allison.
I switched to Singapore with my oldest when he was starting Bigger and in 3rd grade. He started with level 2A. Now I've also started from the beginning with Allison in LHFHG this year. (So I haven't done all the levels...but several of them now.) Maybe you want to check that you're starting on the right level with her, too. We switched from Saxon, and after Grant had completed their 2nd grade math and done very well with it...he placed into level 2A/B with Singapore. The word problems in Singapore, especially, require much more thought than other math curriculums I've seen. There are fewer problems, but the child will really have to think to do them. I prefer this way of doing math, but it will take a child a bit to get into it and get used to having to think. So, just because your daughter is ready to begin 2nd grade with Abeka would not necessarily mean that she's ready for 2A in Singapore. That may have had an effect on how much she enjoyed it.
Here's a thread where Carrie shares why HOD chose to use Singapore math in their guides...
viewtopic.php?f=10&t=112 You already know though that if your family prefers something else that HOD most definitely works just fine with that. I know I was glad that I gave it a try for my family!

So, you could always give it a go once more and see if it worked before going back to Abeka.
