Understanding a repeating pattern involves identifying the smallest unit that recurs in a sequence of objects, shapes, colors, sounds, letters, or numbers, and using that unit to determine missing or following elements. The learner distinguishes repetition from a pattern that grows or changes, including common units such as AB, AAB, or ABC; formal algebraic rules, modular notation, and generalized periodic functions are beyond this scope.
A repeating pattern is a group of objects that repeats in the same order. The smallest group that repeats is called the pattern unit.
Look at this pattern:
š“ šµ šµ š“ šµ šµ š“ šµ šµ __
Step 1: Look for a group that repeats.
The colors repeat like this:
š“ šµ šµ | š“ šµ šµ | š“ šµ šµ
Step 2: Find the smallest repeating unit.
The unit is:
š“ šµ šµ
This is an ABB pattern: one red circle followed by two blue circles.
Step 3: Continue the unit.
After š“ šµ šµ, the unit starts again with š“.
So, the missing circle is:
š“
The completed pattern is:
š“ šµ šµ š“ šµ šµ š“ šµ šµ š“
Remember: In a repeating pattern, the group stays the same. If the objects get bigger, longer, or change in another way, the pattern is growing instead of repeating.
