Imagine you are opening mystery packs of game cards, and every single pack contains exactly 3 cards.
How can one simple pattern look like a math sentence, a list of numbers, and a picture on a grid all at the same time?
The Rule
A rule is a math recipe that tells you how to calculate an output number from any starting input number.
For our card packs, the rule is simple: total cards = number of packs × 3.

How do we organize all these answers without losing track of our counts?
The Table
A table organizes our inputs and outputs into neat rows and columns so we can easily spot the step-by-step pattern.

What happens if we turn each row of our table into a point on a map?
The Graph
A graph shows the relationship as dots on a grid, using an x-axis along the bottom and a y-axis going up the side.
