The Coordinate Plane

Playback speed:
A treasure map says: start at the rock (0, 0). Dig at (−3, 2). Which way do you walk?

In this video

  • Meet the four quadrants and the origin.
  • Plot (−3, 2): walk left 3, then climb up 2.
  • Reflect a point across the x-axis and the y-axis.

Try it together

Which quadrant is (−5, 8) in?
Show the answer
Quadrant II
x is negative (walk left) and y is positive (climb up).

Ask, don't tell

“Which number do we use first?”

“Which way does a negative number make you go?”
