Lesson plan(s)

Area Explorer
This is a simple program that allows students to explore the area of rectangles and irregular shapes.
 
Perimeter Explorer
This is a simple program that allows students to explore the perimeter of rectangles and irregular shapes.
 
Shape Explorer  

Introduction to Geometry for Primary Students
These lessons are designed to guide young children through an introduction to geometry. Children will learn to recognize shapes and to create patterns, and will explore spatial relations and symmetry.

 
Investigating the Concept of Triangles and the Nature of Polygons
A two-part geometry lesson using interactive geoboards.
 

Polygon Playground
Create shapes and pictures using polygons.

 
Shape Tool  

Mirror Tool
This Java applet helps students investigate symmetry. Mirrors can be used to create reflection symmetry. Allows you to create manipulate shapes in several different ways. You can draw, color, paste, slice, rotate, reflect, expand, and contract.

 
Investigating the Concept of Triangle and the Properties of Polygons: Making Triangles  
Tessellate  

Turtle Pond
A turtle logo-based activity for developing geometry concepts.

 

Hiding Ladybug
An activity for developing geometry concepts by creating paths and navigating mazes for young students.

 

Cubes Applet
An applet that supports student explorations of volume by allowing the to build the prisms that match a net.

 

Geometric Solids
An applet that allows you to explore the properties of 3-dimensional polygons, such as edges, corners and faces.

 

Isometric Drawing Tool
Virtual isometric drawing paper for exploring 3D shapes
