Greetings Falcon Math Stars,
This guide is to help you know what vocabulary you should be using daily in your
classrooms. This guide matches the Henrico County Public Schools’ pacing guide. The
included words are vocabulary for your students to know, as well as words that you should
be using in the discussions and instruction in your rooms.
Please feel free to add to the list. If there are any words that you feel need to be added
please send them to the entire department. While it is important that you look at your
course’s words, I also ask that you skim through the other courses. We need to see where
our students are coming from, where they need to be, and where they are going. It is very
important that we are all using the same vocabulary. A lot of the issues our students are
dealing with in math can be dulled with good vocabulary usage and solid math discourse.
Feel free to see me with any questions on the attached vocabulary. I am here to discuss and
help you implement the use of these words. I even have a great book on how to increase
mathematics literacy.
I hope to see you all using this vocabulary in your daily lessons.
Respectfully,
Charmelle W. Washington
Math Coach
