Vocabulary Cards and Word Walls

Important Notes for Teachers:

The vocabulary cards in this file reflect the vocabulary students taking

Coordinate Algebra will need to know and be able to use.

The cards are arranged alphabetically.

Each card has three sections.

o Section 1 is only the word. This is to be used as a visual aid in

spelling and pronunciation. It is also used when students are writing

their own “kid-friendly” definition and drawing their own graphic.

o Section 2 has the word and a graphic. This graphic is available to be

used as a model by the teacher.

o Section 3 has the word, a graphic, and a definition. This section can be

used for the Word Wall in the classroom.

These cards are designed to help all students with math content vocabulary,

including ELL, Gifted and Talented, Special Education, and Regular

Education students.
