Cartesian Coordinate Plane Lesson
Cartesian Coordinate Lesson Plan
Abstract
This lesson combines using Shodor's computer applets with a fun hands-on activity.
This lesson not only teaches basic coordinate plane manipulation, but also transforms
any classroom or outside area into a three dimensional coordinate plane.
Standards (NCTM 3-5)
Algebra
Understand numbers, ways of representing numbers, relationships among numbers, and
number systems
- explore numbers less than 0 through extending the number line and through
familiar applications
Geometry
Specify locations and describe spatial relationships using coordinate geometry and
other representational systems
- describe location and movement using common language and geometric vocabulary
- make and use coordinate systems to specify locations and describe paths
- find the distance between points along horizontal and vertical lines of a
coordinate system.
Student Prerequisites
Technological:
Students must be able to:
- perform basic mouse manipulations such as point,
click and drag
- use a browser such as Netscape for experimenting with
the activities
Teacher Preparation
Have a classroom or an outside area sectioned off into a coordinate plane
Students will need:
- Access to a browser
- Graph paper and pencil
Lesson Outline
- Focus and Review
Review any pertinent vocabulary and express to the students that today they will be learning
about the Cartesian Coordinate Plane.
- Objectives
Students will be able to identify points on 2 and 3 dimensional Carteasian Coordinate Planes.
- Teacher Input
- Guided Practice
- Have students work in pairs to complete 5 problems from the Simple Coordinate
Game applet.
- Have students draw the problems given to them by the applet and record their answers beside
their drawings to ensure each group finishes all 5 of the problems .
- Walk around the class, monitor student progress, and answer any student's questions.
Teacher Input
Guided Practice
- Have students, working in pairs, play the Simple Maze Game.
- Walk around the class, monitor student progress, and answer any student's questions.
Teacher Input
- Explain how to locate objects in all quadrants of the coordinate plane. If your students
have never been introduced to negative numbers, you may need to lead a discussion
about negative numbers.
Guided Practice
- Have students work in pairs to complete 5 problems from the General Coordinate
Game applet.
- Have students draw the problems given to them by the applet and record
their answers beside their drawings to ensure each group finishes all 5 of the problems
completing the 5 problems .
- Walk around the class, monitor student progress, and answer any student's questions.
Teacher Input
Guided Practice
- Have students, working in pairs, play the Maze Game.
- Walk around the class, monitor student progress, and answer any student's questions.
Teacher Input
- After the students show an understanding of the x-axis and y-axis introduce
them to the z-axis.
- Have the classroom marked off in a grid with different letters posted throughout
the room.
- Explain to the students that their list of coordinates will spell a
mathematician's name.
- Tell students once they have figured out who their mathematician is they
are to investigate their mathematician's importance using books you supply or by doing
an Internet search.
- Independent Practice
- Have the students demonstrate their knowledge of the coordinate plane by locating
assigned points. These points should be scattered throughout the
classroom
- Have the students complete their research and present their findings about their
assigned mathematician to the class.
- Closure
- Review the x-, y-, and z-axis.
- Review the concept of negative numbers if this was the first time students
have been introduced to them.
