Basic patterns
Express patterns in words, numbers, and shapes, and check new cases.
Meaning
Studying patterns means finding and explaining repeating or regularly changing relationships. After conjecturing a rule from a few terms, state the conditions under which it applies.
Example
In a repeating red–blue–blue pattern, the eighth position is blue, like the second position. Dividing 8 by 3 leaves a remainder of 2. A few initial values do not uniquely determine what follows. Check whether a repeating rule or construction method is given.

Learning goal
Express patterns in words, numbers, and shapes, and check new cases.
Helpful background
Observe the order in which numbers or shapes appear.
