8th Grade Math

Algebra foundations, geometry, and mathematical modeling for eighth grade students.

Practical Applications

Geometry in Construction and Design

Building with Geometry

Geometry is everywhere in construction and design—from measuring rooms to designing parks.

Measuring Spaces

Use area and perimeter to figure out how much carpet you'll need or how much fence to buy.

Creating Patterns

Designers use shapes and angles to create cool patterns in tiles, windows, and art.

Real-World Example

To build a rectangular garden that's 5 meters long and 3 meters wide, calculate the area (\(5 \times 3 = 15\) m²) to know how many plants can fit.

Examples

  • Designing a triangular flag with sides 3 m, 4 m, and 5 m using the Pythagorean Theorem.

  • Calculating the amount of paint needed to cover four walls using surface area.
