## Chapter 1

### INTRODUCTION

The local art gallery has decided to set up a new display that will be called "PATTERNS ALL AROUND US". The art gallery curator has read that there are many different kinds of patterns that are used by many people in the world. She wants the gallery display to show visitors that patterns are important and interesting by displaying number patterns and non-numerical patterns of all kinds.

Your class has been hired by the art gallery to create the "PATTERNS ALL AROUND US" display. Each person in the class is to create and display 2 patterns, along with a description and/or an explanation of each. The patterns should be ready to be displayed in art gallery for the public to see.

### THE PROCESS

1. Look through the websites for examples of one number pattern and one non-numerical pattern that you think will interest the visitors at the art gallery.
1. Investigate Number Patterns. Click on EXPLORER and then click on PATTERNS. Go to this page and explore the following activities:

Trick with a Calendar
Squares on a Chessboard
Powerful Number Patterns
Complete the activities to explore new patterns.

2. Investigate The Number Bracelets Game website to look for examples of patterns. Look at the Animal Patterns   website and the Patterns at the Museum website for example of non-numerical patterns.

2. Complete the activities at the websites that interest you the most.
3. Create two patterns. Be sure that one is a number pattern and one is a non-numerical pattern.
4. Write a description that will be attached to the pattern for visitors to read. You might tell the reader:
1. The name of your pattern.
2. How the pattern was made? What are the changing attributes of the pattern? What is the rule for the pattern?
3. Why did you decide to make a pattern like this? What would you like the visitor to notice about your pattern? What makes the pattern interesting?

5. Decide on an interesting way to display the pattern and prepare it for the class to see.
