I have been using HOD for one year now with my kiddos

, but only switched my three younger kiddos to Singapore last spring. My 11 DD is using TT 5 happily, but I am not seeing her understanding of math increasing very much. I just got back her ITBS scores, and she didn't have a one grade jump up in math. Normally that would be find, but with this love, she is already a little behind in math. I am pondering switching her over to Singapore and doing 4A, 4B, & 5A with her for 6th grade, and then doing 5B, 6A, & 6B for 7th. I don't want to over react to the standardized test scores

, but I also want to help her have a solid foundation in math before heading into advanced math. Anyone made a switch to Singapore to help an older child firm up their math foundation? I would love to hear your insight!
