Materials highlight, define, illustrate, and show the purpose for mathematical language within the context of the lesson (not in isolation).

Materials guide teachers encourage students to build their own understanding of mathematics actively, using language to actively build their own understanding of mathematics, using language, through sustained activities and experiences.

Materials provide strategies to help students make connections between current language, new language, and mathematical concepts.

Units offer repeated opportunities to develop, refine, and extend language for mathematical purposes over time

Teacher materials state clear and specific language objectives both for math practices as well as for academic purposes that cut across disciplines

Student materials contain mathematics and language learning objectives.

Teacher materials articulate a pathway or progression of objectives for content, practices, and language throughout units

Materials present opportunities for students to use language at different stages within a unit, such as speculating or predicting about a new topic, exploring and reflecting during an experience, presenting afterwards, etc.

Activities deepen and extend learning through the various modes of communication: speaking, listening to deepen and extend learning through varied modes: speaking, listening, reading, and writing

Materials include prompts for students to reflect on their own thought processes, language use, methods, and learning of mathematical content

Materials encourage students to utilize interdisciplinary words and phrases as well as math-specific words and phrases.
