The current English Language Teaching (ELT) global coursebook market has embraced content and language integrated learning (CLIL) as a weak form of bilingual education and an innovative component to include in General English coursebooks for EFL contexts. In this paper, I investigate how CLIL is included in ELT coursebooks aimed at young learners, available to teachers in Argentina. My study is based on the content analysis of four series, which include a section advertised as CLIL oriented. Results suggest that such sections are characterised by (1) little correlation between featured subject-specific content and school curricula in L1, (2) oversimplification of contents and (3) dominance of reading skills development and lower-order thinking tasks. Through this study, I argue that CLIL components become superficial supplements rather than a meaningful attempt to promote weak forms of bilingual education.
