Estimating
Making a reasonable guess about a number or measurement

Rounding Numbers

What: Process of adjusting numbers to convenient nearby values
Why: Essential for quick calculations and estimates
How does it help: Builds mental math skills and number sense

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

Estimation

What: Practice making educated guesses about quantities
Why: Crucial for real-world problem solving
How does it help: Develops confidence in making mathematical judgments

There are several types of symmetry in mathematics:


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

Approximate Values

What: Working with rough calculations rather than exact ones
Why: Important for practical everyday math
How does it help: eaches efficiency in mathematical thinking

Tessellations can be created using:


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