These words are used throughout the year in geometry and are also used in my ABC Book Lesson Plan. Through the year the students enter these terms into their notes as we go through the various chapters and then also use the words in various ways to help them learn the term, the definition, and application of the term. Some of the ways we have worked with the terms are listed below:

Worksheets

Index card spiral book – terms are added to the spiral notebook (one on

each card) with the definition and a sketch. The spiral index card book can be added as the year progresses and also can be used to review at any time easily.

Student written questions

Playing charades – terms for the chapter and/or from the word list are

written on index cards and distributed to the students. The students then take turns acting out the terms. Some terms are very difficult to act out which makes this fun and challenging.

Using PowerPoint or the SmartBoard students identify the terms based on

a single picture or sketch or construction.
