Coordinate Plane
Coordinate Plane Lesson Plan
Abstract
Make learning how to use the Cartesian Coordinate plane fun by using computer applets.
This lesson combines using our computer applets to learn basic coordinate plane manipulation
with a fun hands-on activity which transforms any classroom 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 by 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 to 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 the class 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 tell the students that today they will learn
about the Cartesian Coordinate Plane.
- Objectives
Students will be able to: identify points on 2 and 3 dimensional carteasian coordinate systems.
- Teacher Input
- Guided Practice
- Have students work in pairs and complete 5 problems from the Simple Coordinate
Game applet.
- To check the students' progress, have them draw out the 5
problems and record their answers beside their
drawings.
- Walk around the class, monitor student progress, and answer any student questions.
Teacher Input
Guided Practice
- Have students work in pairs and play the Simple Maze Game.
- Walk around the class, monitor student progress, and answer any student questions.
Teacher Input
- Explain how to locate objects in all quadrants of the coordinate plane. You
may need to lead a
discussion on negative numbers.
Guided Practice
- Have students work in pairs and complete 5 problems from the General Coordinate
Game applet.
- Monitor students progress by having having them draw out 5
on graph paper, and record their answers
beside their drawings.
- Walk around the class, monitor student progress, and answer any student questions.
Teacher Input
Guided Practice
- Have students work in pairs and play the Maze Game.
- Walk around the class, monitor student progress, and answer any student questions.
Teacher Input
- After the students show an understanding of the x-axis and y-axis, introduce
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
mathematicians name.
- Also tell students once they have figured out the identity of their mathematician; they
are to investigate their mathematician's importance by using books you supply or doing
an internet search.
- Independent Practice
- Have the students demonstrate their knowledge of the coordinate plane by locating
the points they have been assigned which should be scattered
throughout the class.
- Have the students complete their research on their mathematician
and present to
the class why their mathematician was important.
- Closure
- Review the x-axis, y-axis, and z-axis.
- Review the concept of negative numbers if this was the first time students
were introduced to them.
