Sample Standard: Plot
points in the coordinate plane
Grade Level: Pre-Algebra,
Algebra I
Time: 20 minutes
Materials: Pre-printed coordinate plane
for each student
Colored
pencils
Group size: Any
Purpose: To use
during a unit on coordinate planes as a revisiter.
Activity:
Students are given a coordinate plane and are
asked to mark four coordinates in a row with dots. The dots may go in any
direction. Students are encouraged to make their "line" unique from other
students around them.
Ordered pairs of coordinates are drawn from a
hat and read aloud by the teacher.
Students mark the points on their coordinate
planes with an X in "bingo style."
Points continue to be called until one student
marks out their original dots and says, "Four dots in a row."
The student then reads the ordered pairs they X'd
out back to the class.
Small prizes may be awarded.
The coordinate planes can be of any size depending on the
amount of time available.
Modification for
Above-Level students:
1. After play is completed, students identify the
slope and y intercept of their line.
2. Students write the equation of the line
connecting their dots.
Modification for Lower-Level
students:
Restrict the coordinate plane to quadrant one.
