ELSF’s research-informed guidelines support content developers in building their capacity to design, develop, and refine curriculum materials that effectively support multilingual learners. The Math Guidelines provide the necessary foundation for the simultaneous development of disciplinary knowledge, language and math literacy for multilingual learners. They can also be applied to existing math curriculum to assess how responsive it is to multilingual learners' needs.

The Guidelines were developed iteratively with researchers, practitioners and experts. They are divided into five areas of focus. Each area is comprised of several guidelines that are explored in depth through specific attributes, providing content developers with actionable solutions to support multilingual learners.
