I am sitting with DD today doing the placement tests for singapore math. She's got some obvious gaps which are to do with being taught a different curriculum thus far. I know the standard advice is to buy the whole set of books if there are consistent gaps in a particular area, but I am wondering about just teaching those areas and moving on to higher level books. It seems crazy to buy a whole curriculum for one or two areas that she just haven't covered yet but will clearly pick up in a snap. For example she's clearly not ever seen number bonds represented the way they are in the test she's just done, but she actually knows all of those number pairs and will understand the second it's explained what was actually required.
My only concern is whether the placement test really do indicate all the areas covered and I can just work independently on covering the one or two areas she clearly hasn't seen before?
