Anyone know of k-12 English textbook companies that would fit in the learning context of international schools? We currently use Mcdougal Little but I believe that it books, especially grammar and writing, do not target the skills our students lack in. These textbooks target NS and not NNS though I try to tailor it to my students's needs. One such example is that the usage of prepositions and collocations are not present at all and students have never known or studied b4 collocations although these are significant when studying second language.
Any help will be appreciated
