I keep reading that with Singapore math "you need to add drill". Is this true? Does HOD add the necessary "drill" (I know they add activities with the math for the earlier programs, but what about with later programs?). Is a resource suggested for the "necessary drill"? OR, is no standard extra drill needed in the opinion of HOD? Just curious where HOD stands on this exciting issue.

Second, I read a review that was posted here and at HSR(annegirl or something like that) and it said one of the reasons she liked HOD because(and I am paraphrasing here) she never had to worry about covering what was required for each grade. I own a book that tells you what you "should be" learning for each grade level, for every subject. I'm not saying that you have to learn certain things every year and we all have to agree on everything, but it doesn't hurt to follow some sort of guideline IMHO. I had some idea that I should pull my book out and compare it against HOD every year, but do I really need to? (Because, I am lazy and don't want to bother!) Does Carrie have some sort of "list" she uses when she's writing each program? IE, you should cover such and such in K, and then she writes those "skills" into LHFHG etc? Again, I am just curious because I am going to throw my book out the window and just believe Carrie has it covered (if that is the case).
These questions are probably really silly

Thanks for any input in advance!
