Often, in mathematics education, we forget how many connections we can make to language arts. The metrical patterns of poems and the syntactic patterns of how we make nouns plural or verbs past tense are both word patterns, and each supports mathematical as well as natural language understanding.
Language gives teachers of multiple subjects an interesting way to cross disciplines.
In Limerick Factory you make limericks online and figure out why they work. At the Syntax Store you work with parts of speech even if you don't know what they are or precisely how they function. Almost all students have mastered one language or another. And language has some of the most sophisticated patterns we can imagine. As soon as young students can read, they can play Limerick Factory and Syntax Store, regardless of whether they understand all aspects of the activities.
