Number and Operations

Overview

The purpose of these resource materials is to provide K – 8 educators with explanations
and examples that facilitate understanding of the mathematics in the Grade-Level
Expectations (GLEs)*. These resource materials are organized by content strand and by
GLE “stems.” The definitions and explanations within each section are not alphabetized,
but are organized to parallel the introduction of new concepts and skills within each GLE
“stem” across grades. The materials contained in this document focus on the Number
and Operation strand and only address the NECAP GLEs that are common to all three
states.

To facilitate access, each definition is coded (e.g., N&O – 4, the 4^th definition for the
Number and Operations strand). There are multiple tables of contents: 1) An overall table
of contents on page 3 contains all the terms or phrases defined for the content strand in
alphabetical order ; and 2) A table of contents for each section in alphabetical order. In
addition, if there is a word or phrase that you are unclear about within a definition, check
the overall table of contents to determine if the word or phrase is defined in another
location in this document.

Note: Examples are provided throughout this document to illustrate definitions or phrases
used in the mathematics GLEs. However, the kinds of questions students might be asked
in instruction or on the NECAP assessment about the mathematics being illustrated are
NOT necessarily limited to the specific examples given. It is the intent, over time, to add
released NECAP items to expand the set of examples.

Please send comments, corrections.

* Grade-Level Expectations are called Grade Expectations (GEs) in Vermont.
