Polygons
A polygon is a 2 dimensional shape which: - is closed - all sides are straight
Examples of Polygons
Activity: Hunting polygons
Explore the playground in draw 3 different things representing polygons.
WEEK 4
VALUE: The only way of having friends, is being one.
TOPIC: PROPERTIES OF POLYGONS
CLASS PLAN:1. Orientation 2. Symmetry 3. Interactive examples 4. Activity 5. Closing
Orientation
A polygon rotated is still the same.
Symmetry
A polygon has symmetries if you can cut (straight) it in 2 equal parts
Interactive resource https://www.geogebra.org/m/chbfzetv
Activity
Draw the following polygons in different orientations, and their lines of symmetry.
WEEK 5
VALUE: A friend is someone with whom you dare to be yourself.
TOPIC: POLYHEDRA

DefinitionA polyhedron is a 3 dimensional object with: - Vertexes - Edges - Right faces
All faces in a polyhedron are polygons.
Illustrative Examples
Classification
- By shape: Regular if all faces are regular, and irregular if not.
- Prism: if it has 2 equal bases connected.
- Pyramind: if all vertexes of a basis are connected to a common vertex
Examples by Shape
Regular
Irregular
Examples of Prisms
Examples of Pyramids
