This activity will help students make sense of the idea of equivalence in Algebra. This is a fundamental concept behind simplifying expressions, a core topic in the curriculum. The graphical representation of a function can anchor students understanding of what they are doing when they simplify.
Before the Activity
If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.
Make sure you are familiar with the following TI-Navigator™ system functions: Quick Poll and Activity Center
Download the attached activity resource file to your computer
During the Activity
Practice simplification techniques in reverse, gaining comfort with algebraic manipulation
Build a sense of equivalence, indicated by identity of graphs
After the Activity
Assess your students understanding by using the Quick Poll feature as desired
