Introduction to graphing with negatives on the y-axis only. Students are better able to focus on (x,y) and (x,-y) by interpreting quadrant 4 as jumping "down" into water, compared to quadrant 1, which was jumping "up" into the air. Includes guided practice with keys, and five original graph art puzzles with full size keys. Kid friendly language and high-interest images. Leveled by difficulty (higher puzzle numbers are more difficult). Unlimited copy rights allowed within the teacher's classroom.
