Patterns That Repeat

A repeating pattern is a design where the same colors, shapes, or objects appear over and over in the same order.

Reading is good — doing is better. Practice Patterns That Repeat as an interactive lesson.

Definition

A repeating pattern is when you take a group of things — like shapes, colors, or objects — and keep copying that exact group again and again in a line or across a design. The group that repeats is called the core of the pattern.

Remember the rule

Find what repeats, circle the core, then copy it — the pattern never changes order!

Key words

Pattern: A design where things happen in a predictable order that you can follow.
Repeat: To do the same thing again and again in the same order.
Core: The small group of colors or shapes that gets copied over and over to make the pattern.
Unit: One complete copy of the core — for example, one red-blue-yellow set before it starts again.
Element: Each single item in a pattern, like one circle or one stripe.
AB Pattern: A pattern that uses two things that trade off, like red-blue-red-blue.
ABC Pattern: A pattern that uses three different things in order, like circle-square-triangle-circle-square-triangle.
Predict: To figure out what comes next in the pattern before you see it.

Worked examples

Red, Blue, Red, Blue, Red, ___

→ Blue · This is an AB pattern. The core is Red-Blue, and it just keeps going.

Circle, Square, Triangle, Circle, Square, Triangle, Circle, ___

→ Square · This is an ABC pattern. After Triangle, you go back to the start of the core.

A student stamps a row of stars and hearts across their paper: Star, Heart, Star, Heart, Star, Heart. What shape comes next?

→ Star · The core is Star-Heart. Count the elements — every odd one is a Star.

A border on a painting goes: Stripe, Dot, Dot, Stripe, Dot, Dot, Stripe, ___

→ Dot, Dot · The core is Stripe-Dot-Dot. When you see Stripe again, you know two Dots follow.

Look at this pattern: Yellow, Green, Green, Blue, Yellow, Green, Green, Blue. What are the next two colors?

→ Yellow, Green · The core is Yellow-Green-Green-Blue. After Blue, start the core over with Yellow.

A student wants to make a repeating pattern with only triangles. She uses big, small, big, small. Is this a pattern?

→ Yes! Big and small count as two different elements, so the core is Big-Small and it repeats. · Patterns do not have to use different colors — size and shape work too.

Common mistakes

Stopping too soon — drawing the core only once and thinking the pattern is done. A pattern must repeat at least two or three full times.
Changing the order in the middle — for example, starting Red-Blue-Red then switching to Blue-Red-Blue. The order must stay exactly the same.
Skipping an element — leaving out one shape or color by accident so the pattern breaks.
Thinking a random row of shapes is a pattern. There must be a rule that repeats, not just any mix of shapes.
Confusing the whole design with the core — the core is just the small group that repeats, not the entire finished pattern.

FAQs

How do I know where the core ends?

Say the pattern out loud slowly. When you hear the same sounds start again, that is where one unit ends and the next begins. For example: Red-Blue — Red-Blue. The dash shows where the core ends.

Can a pattern have more than three things in its core?

Yes! The core can be two, three, four, or even more elements long. As long as that exact group keeps repeating, it is still a pattern.

Does a pattern have to go left to right?

No. Patterns can go left to right, top to bottom, up and down, or even in a circle. What matters is that the core repeats in order.

What if I am not sure what comes next?

Go back to the beginning and find the core. Circle or underline it. Then ask: which part of the core comes next in line?

Is a checkerboard a repeating pattern?

Yes! A checkerboard uses the core Black-White (or Red-Black) and repeats it across every row and column, making a pattern that goes in two directions.

Why do artists use repeating patterns?

Repeating patterns make art look organized and beautiful. They are used in fabric, pottery, wrapping paper, and borders because the eye loves following a predictable rhythm.
