Understanding Patterns, Relations, and Functions

A relation in mathematics is a set of ordered pairs, while a function is a specific type of relation where each input is associated with exactly one output. Representing and analyzing patterns and functions using various methods such as words, tables, and graphs is essential for students in grades 3-5.

Understanding Patterns, Relations, and Functions

FUNCTIONS

Functions are a special kind of relation .
At first glance, a function looks just like a relation.

EXAMPLE:{ (0,1) , (5, 22), (11,9) }

Like a relation, a function has a domain and range made up of the x and y values of ordered pairs.

RELATIONS

A relation is just a set of ordered pairs.
Some Examples of Relations include { (0,1) , (55,22), (3,-50) } { (0, 1) , (5, 2), (-3, 9) } { (-1,7) , (1, 7), (33, 7), (32, 7) }

Note: { } are the symbol for "set"

DIFFERENCES BETWEEN RELATION AND FUNCRTION

In mathematics, what distinguishes a function from a relation is that each x value in a function has one and only ONE y-value.

Geometric And Numeric Patterns

Common Number Patterns
An Arithmetic Sequence is made by adding some value each time.

Example: 1, 4, 7, 10, 13, 16, 19, 22, 25, ...

This sequence has a difference of 3 between each number. The pattern is continued by adding 3 to the last number each time.

Grades 3–5 Expectations:

represent and analyze patterns and functions, using words, tables, and graphs.
describe, extend, and make generalizations about geometric and numeric patterns;
