Introduction to Patterns

Note: Calculators will be helpful to students during this unit.

"Today we are going to start talking about and working with patterns. Patterns are all around us. We see them everywhere we go. We see them in clothing, wallpaper, any kind of print usually has a pattern, we could go on and on. But one of the other places that we see patterns is in mathematics."

"In mathematics, patterns can be either numbers, letters or shapes. The important thing to remember is that there are all kinds of patterns, and your job is often to figure out what the pattern is."

"Before we start working on solving patterns and continuing patterns, here are a few notes. Here are some vocabulary words that you are going to need when working on patterns."

On Board: 1. Sequence- a series of numbers, shapes or letters that fall in a particular order.

Difference- means the operation subtraction

Term- a number, letter or symbol used in mathematics
Pattern- a sequence of terms where each term is related to the other terms in some way.
