Study Notes

Patterns in Nature and Daily Life

Examples of patterns in nature include zebra's stripes, spider's web, honeycomb, and snowflakes.

Definition of Pattern

A pattern is something that happens in a regular and repeated way, a repeated form, recurring form or design.

Importance of Pattern Finding

Pattern finding has led to the development of mathematics and helps students identify relationships, find logical connections, and make predictions.

Symmetry

Symmetry indicates that an object can be divided into two identical parts, such as the left and right sides of a face.
Types of symmetry include line symmetry (bilateral symmetry) and rotational symmetry.
Rotational symmetry is when a figure can be rotated by a certain angle and still appear the same, such as a starfish.
The angle of rotation is the smallest angle that a figure can be rotated while still preserving its original formation.

Mathematical Concepts

Mathematics is a way of looking at the world and nature, and studying patterns helps develop problem-solving skills.
Arithmetic sequences and other types of sequences, such as the Fibonacci Sequence, can be used to identify and articulate patterns.

Lesson Objectives

Recognize that mathematics permeates the world around us.
Appreciate the usefulness, power, and beauty of mathematics.
Enjoy mathematics and develop patience and persistence when solving problems.
Identify patterns in nature and regularities in the world.
Illustrate the importance of mathematics in one's life.
