Absolute Value of Linear Functions
Students identify and interpret how absolute value affects linear functions. They also graph linear functions and reflect them in a line of symmetry. Finally, students evaluate the absolute value of a constant using technology to...
Curated OER
Symmetry
Students examine the concept of symmetry. They use photographs in front of a mirror to see symmetry. They write an explanation or drawing of how a mirror always produces a line of symmetry.
