Math Examples: Area with Pattern Blocks: Example 9

Topic

Geometry

Description

This example shows a square with an area of 1 square unit and a composite figure made up of a central square and four surrounding triangles forming a star-like shape. The triangle's side length equals that of the square, contributing an additional sqrt(3) units for a total area of sqrt(3) + 1 square units.

The use of pattern blocks facilitates understanding geometric concepts such as area by allowing students to manipulate shapes physically. This collection illustrates how various configurations can enhance comprehension of spatial relationships and arithmetic operations involving areas.

The availability of multiple worked-out examples aids students in grasping geometric principles thoroughly. Each example presents unique challenges that encourage creative application and recognition of consistent patterns across different scenarios.

Teacher Script: "Consider this star-like shape around a central square. The triangles have sides equal to those of the square. Let's calculate how much more area these triangles add to our central square."
