9/23 Mon: Reflections Across the X Axis

HW: page 121 (#s 2 and 3), page 122 (#s 1-3, 6, 8, and 9)

Learning Target: I can reflect simple points across the X and Y axis and differentiate between them using prime notation. 

AGENDA:
DIN: 10.0 sheet on graphing
1. Review HW
2. Review graphing points on mini-coordinate plane and play Battle Ship with a partner!
3.  Reflection across the X axis

• Use another sheet of graph paper to set up the coordinate plane the same.  Be sure to label the axes and the x and y axes.  
• label the axis
• label the integers on both number lines (the axes) up until 7 on each end (positive and negative)
• graph the following point E (-3,-4).  Write the coordinates on the graph below. 
• Notice what quadrant the point is in. 
• Fold the paper exactly on the line of the X axis.  
• heavily shade over the back of the point.
• open the paper up. What happened? 
• Which quadrant is the new reflection point in?  
• Write the new coordinates under that point on the bottom half of the graph paper.  Label this point with prime notation

NOTE: If you draw two images, use DOUBLE PRIME NOTATION to indicate which image came first and second.
