Lighthouse Initiative for Texas Classrooms

An Example of Scope and Sequence for Calculator Skills

Developed by Carol B. Brown, Saint Mary's Hall, San Antonio, TX

Statement of philosophy: The graphing calculator is a tool to be used in mathematics and science classes. It is not an end in itself. Skills that are enhanced or reinforced by the graphing calculator should be practiced on a regular basis at all levels. Use of the calculator should not mean that students do not learn basic mathematical operations or graphing skills.

Question 1: When is it appropriate to introduce students to the graphing calculator? Answer: Grade 6 with classroom sets of calculators. Starting with grade 7, all students may be required to purchase a TI 83, a TI 83+, or a TI-83+silver. This calculator will be satisfactory for all work done through grade 12.
