I use this activity in the beginning of the school year when introducing terminology such as angles, lines, segments, measures, perpendicular etc.
The original material is from the SIMMS Integrated Mathematics Using Technology, I have adapted the activities to fit my objectives. Students have been introduced to using Cabri jr on the calculator, but the sequence of steps are provided for user-friendliness.
Before the Activity
Students should have access to either the TI-83 or TI-84 family of calculators.
During the Activity
Students will review properties of Reflections.
After the Activity
Review student answers:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
