Reflection: ELL Students Subtraction - The Equal Change Algorithm- It's Fun! - Section 4: Wrap-up


Over the years, I have gotten into the habit of weaving new vocabulary into all content areas and lessons. It's essential for all students, but especially key for English language learners whose initial period of vocabulary development occurred in a non-English language.

I do often plan ahead for the vocabulary lessons (for example, when I preview a text I'll be reading with the class) but there are also numerous occasions throughout the day when it's just natural to include mini vocabulary talks.  The word differ in the math context of the wrap-up question provides a moment in which it's logical to talk about a few more examples of math words that have both a verb and a noun form. 

differ (v)             difference (n)

total (v)               total (n)

group (v)             group (n)

If there is time, I ask students what other examples they can think of, and if the examples they generate aren't mathematical, I focus more on the fact that they are identifying different properties of words than that they fell out of category.
