If you read through the Ready Reference Guide, the Sisters suggest some language that might help students build that understanding of the strategy. I think we want to keep the language we use for the strategies as close as possible to the menu, and I think for the most part, the kids can understand the terms after we spend time modeling and discussing what it means.
Certainly, adding your own language you feel they are comfortable with or can relate to as you are introducing is appropriate and necessary :). It's like introducing new vocabulary--after a bit of time they will get it. I love how our first grade kids have picked up on the words "strategy, stamina and independence"--and use them effectively :).
