"...a glossary of terms selected to support the learning outcomes identified in the Mathematics Program of Studies. The glossary is designed for teachers to use with their students. A term that appears in multiple grade groupings will have grade appropriate information to illustrate the term. Many of the terms in the earlier grades will have real world examples, and many of the terms at all grades will have applets and/or animations to support student learning."
Note: At this point, there are a lot of "under construction" entries in the glossary. I hope they fill this out soon!
