Texas Instruments TI-30X Teachers Guide - Page 3

About the Teacher Guide How the Teacher Guide is Organized This guide consists of two sections: Activities and How to Use the TI-30X ÙS. The Activities section is a collection of activities for integrating the TI-30X ÙS into mathematics instruction. The How To Use the TI-30X ÙS section is designed to help you teach students how to use the calculator. Activities The activities are designed to be teacherdirected. They are intended to help develop mathematical concepts while incorporating the TI-30X ÙS as a teaching tool. Each activity is self-contained and includes the following: • An overview of the mathematical purpose of the activity. • The mathematical concepts being developed. • The materials needed to perform the activity. Things to Keep in Mind • While many of the examples on the transparency masters may be used to develop mathematical concepts, they were not designed specifically for that purpose. • For maximum flexibility, each example and activity is independent of the others. Select the transparency master appropriate for the key you are teaching, or select the activity appropriate for the mathematical concept you are teaching. • If an example does not seem appropriate for your curriculum or grade level, use it to teach the function of a key (or keys), and then provide relevant examples of your own. • To ensure that everyone starts at the same point, have students reset the calculator by pressing & and simultaneously or by pressing %  and then selecting Y (yes). • The detailed procedure, including step-bystep TI-30X ÙS key presses. • A student activity sheet. How to Use the TI-30X ÚS This section contains examples on transparency masters. Chapters are numbered and include the following. • An introductory page describing the calculator keys presented in the example, the location of those keys on the TI-30X ÙS, and any pertinent notes about their functions. • Transparency masters following the introductory page and providing examples of practical applications of the key(s) being discussed. The key(s) being discussed are circled on the TI-30X ÙS keyboard. Conventions Used in the Teacher Guide • In the text, brackets [ ] around a key's symbol/name indicate that the key is a second, or alternate, function. For example: Z • On the transparency masters, second functions are shown just as they appear on the keyboard.
