Exploration
Work with a partner.
Partner A:
Draw a rectangle on the coordinate grid. Make sure the area of the rectangle is at least 20 square units. Don't show the rectangle to your partner.
Partner B:
Your goal is to figure out what rectangle your partner drew using the fewest points. Use coordinates to name points in the coordinate grid. Your partner will tell you whether the point is or is not on their rectangle.
