In a training today, I learned about sentence frames. These are helpful for English language learners, and also native speakers, to develop understanding of math concepts by filling in a statement with blanks in it.
In researching this further, I came across a wiki that contains a number of sentence frames for various California math standards categorized by grade level. These can be used in any context to fit your math teaching. You can even contribute your own sentences by joining the wiki.
