(Update 12-04-022) Today a friend told me about another book, prealgebra, which is roughly about a 7th or 8th-grade math textbook in the USA. My daughter (7th grade) is doing the exercises on Afficient (this is a bit like the online version of the good old Kumon).
(Original) In my daughters school, we started this math curriculum about 5, or 6 years ago. One thing I noticed in the US, the kids usually don’t have paper textbooks that they can bring home. My impression is the school usually provide the books when kids are in school, during the class. I also think each teacher can do it in a different way.
For the Math in Focus (a variant of Singapore Math) though, the textbook is available online. Here is the link to get it (this is the Clever portal, note one needs to be in Ladue School and has the right login information in order to access). Once one logs into the Clever portal, go to “think central”, and it has the links to the math textbooks (or student book, exercise book). There is .epub format textbook to download too. Note we have not really taken advantage of the ebook yet. But it’s probably a good idea to know where the textbook is, especially when we try to explain the bar model to the kiddos 🙂
Btw, please note Clever is a single sign on platform in which we can see other apps in addition to thinkcentral. For example, I saw the “Big Ideas Math” there too, which is used by my 6th grader. I am guessing other school districts (or other schools) may use the Clever platform too.
We used to find a place that the old textbook is online. It seems it’s no longer available. For big ideas math, I did see an online book (free, no need for login), for example this is grade 6 book (from a school link here).
Last but not least, we also bought the “big ideas math” (common core) textbook for my older daughter the 6th grader as well. We asked around and bought it online: it’s a bit unusual for book sellers as they usually work with schools (wholesale as opposed to retail). I believe Amazon has math in focus textbook too.
