This is submitted as a power-point, although it is possible to print the document if you intend to use it as an assignment and/or if you plan to assess your students' understanding of Chapter One mathematical language. Included, you will find the Chapter One terms in a format where students can define them either online or for use in a portfolio; you are also provided with the corresponding quiz for vocabulary terms used in most Chapter One texts and an answer key for the teachers' convenience (we KNOW how our time is forever sparse)! Enjoy! Enjoy! ...and thank you!
