Studying number patterns is important for two reasons. First, they help one better understand the concepts of arithmetic and provide a basis for understanding the concepts of more complex mathematics (algebra, trigonometry, calculus). Second, pattern recognition is a useful problem-solving skill, both in mathematics and in real-world situations.

Patterns involving odd and even numbers are investigated. Patterns in multiples of certain numbers lead to an understanding of divisibility rules. Sequences are introduced to heighten sensitivity to patterns and the concept of function is introduced using patterns of number pairs.

* To determine whether a multiplication problem has an odd or even answer.
* To state the divisibility rules for two, three, five, and nine.
* To find the next term in an arithmetic or geometric sequence, given the first three terms.
