Stein - Math 8 Plus - 3.20.17

What We Did Today:

Students started Investigation 3. Problem 3.1 - Flipping on a Grid: Coordinate Rules for Reflections. Students took a basic design element on a coordinate grid and found the rule that generalized reflections based on given lines of symmetry. Students also worked on ACE questions 1 – 3, 8, 16, 26.

 

Focus Question:

How can you describe how points "move" under a reflection with coordinate rules in the form (x,y)→(   ,   ) when the reflection line is (1) the x-axis? (2) the y-axis? (3) the line y=x?

 

Homework:

Finish 3.1 A – C if not completed in class.
