Visual ways to show and explain numbers and information

Bar Graphs

What: Visual displays showing data as rectangular bars
Why: Makes data comparison quick and intuitive
How does it help: Teaches data interpretation and comparison skills

Geometric patterns form the foundation of many mathematical principles and can be observed in various forms:


  • Regular polygons and their properties
  • Tessellations and surface coverings
  • Symmetry in natural and man-made objects
  • Fractal patterns and self-similarity
Geometric Pattern Example

GPie Charts

What: Circular graphs showing parts of a whole
Why: Essential for understanding proportions
How does it help: Helps visualize fractions and percentages

There are several types of symmetry in mathematics:


  • Reflection symmetry (flip)
  • Rotational symmetry (turn)
  • Translational symmetry (slide)
  • Point symmetry
Symmetry Examples

Line Graphs

What: Displays showing how values change over time
Why: Critical for analyzing trends
How does it help: Develops understanding of relationships and patterns

Tessellations can be created using:


  • Regular polygons
  • Irregular shapes
  • Transformed shapes
  • Combined patterns
Tessellation Examples

Data Visualization

What: Various ways to present numerical information visually
Why: Makes complex data understandable
How does it help: Builds data literacy and analytical skills

Famous examples of fractals include:


  • The Mandelbrot Set
  • Koch Snowflake
  • Sierpinski Triangle
  • Dragon Curve
Fractal Examples
