Repeating Patterns
A repeating pattern is a pattern that follows a rule and repeats over and over again. For example: red, blue, red, blue, red, blue. The group red, blue keeps repeating.
In Class 1, children learn to spot patterns, continue patterns, and create their own patterns using colours, shapes, and objects.
Patterns are everywhere! The stripes on a zebra, the tiles on a floor, the beads on a necklace — all follow patterns. When you learn to see patterns, you learn to predict what comes next.
In maths, patterns help us think logically. A child who can spot and continue a pattern is building skills for addition, multiplication, and problem-solving.
What is Repeating Patterns - Class 1 Maths (Patterns (Grade 1))?
A repeating pattern has a core — the smallest group that repeats. The core repeats again and again to make the full pattern.
Types of repeating patterns:
- AB pattern: red, blue, red, blue, red, blue... (2 items repeat)
- ABC pattern: circle, square, triangle, circle, square, triangle... (3 items repeat)
- ABB pattern: clap, stomp, stomp, clap, stomp, stomp... (3 items repeat)
Types and Properties
Types of Repeating Patterns
| Type | Core | Example |
|---|---|---|
| AB | 2 items | red, blue, red, blue, red, blue |
| ABC | 3 items | star, moon, heart, star, moon, heart |
| AAB | 3 items | clap, clap, stomp, clap, clap, stomp |
| ABB | 3 items | big, small, small, big, small, small |
| AABB | 4 items | red, red, blue, blue, red, red, blue, blue |
How to Find the Core
- Look at the first few items.
- Find the group that starts repeating.
- That group is the core.
- Check: does the core repeat exactly through the whole pattern?
Solved Examples
Example 1: Example 1: Find the Pattern
Question: What is the pattern? Red, blue, red, blue, red, blue.
Answer: The pattern is AB: red (A), blue (B) repeats.
Example 2: Example 2: What Comes Next?
Question: Circle, square, circle, square, circle, ___?
Think:
- Pattern: circle, square repeats
- After circle comes square
Answer: Square comes next.
Example 3: Example 3: ABC Pattern
Question: Star, moon, heart, star, moon, heart, star, ___, ___?
Think:
- Pattern: star, moon, heart repeats
Answer: Moon, heart come next.
Example 4: Example 4: Colour Pattern
Question: Ria strings beads: red, red, blue, red, red, blue. What pattern is this?
Answer: This is an AAB pattern: red, red, blue repeats.
Example 5: Example 5: Sound Pattern
Question: Aman claps and snaps: clap, snap, clap, snap. What comes next?
Answer: Clap comes next (AB pattern).
Example 6: Example 6: Complete the Pattern
Question: Big, small, small, big, small, small, big, ___, ___.
Answer: Small, small come next (ABB pattern).
Example 7: Example 7: Create a Pattern
Question: Create an ABC pattern using shapes.
Answer: Triangle, circle, square, triangle, circle, square, triangle, circle, square.
Example 8: Example 8: Fix a Pattern Mistake
Question: The pattern is: circle, square, circle, circle, circle, square. Is there a mistake?
Think:
- Expected AB pattern: circle, square, circle, square, circle, square
- Position 4 should be square, not circle
Answer: Yes, the 4th shape should be a square, not a circle.
Real-World Applications
Patterns in real life:
- Rangoli designs: Colours and shapes repeat in beautiful patterns
- Music: Rhythms follow patterns like ta, ta, ti-ti, ta
- Tiles: Floor and wall tiles often use repeating shape patterns
- Bead necklaces: Beads are strung in colour patterns
- Days of the week: The 7 days repeat every week — that is a pattern too!
Key Points to Remember
- A repeating pattern has a core that repeats over and over.
- AB pattern: two items repeat (red, blue, red, blue...).
- ABC pattern: three items repeat (star, moon, heart, star, moon, heart...).
- To find what comes next, find the core and continue it.
- Patterns can use colours, shapes, sounds, numbers, or objects.
Practice Problems
- What comes next? Triangle, circle, triangle, circle, triangle, ___?
- Find the pattern core: red, green, red, green, red, green.
- Continue: 1, 2, 1, 2, 1, 2, ___, ___.
- What type of pattern is: big, big, small, big, big, small?
- Create your own AB pattern using two colours.
- Priya made a bead necklace: blue, yellow, yellow, blue, yellow, yellow. What comes next?
Frequently Asked Questions
Q1. What is a repeating pattern?
A repeating pattern is a set of items that follows a rule and repeats over and over. The smallest group that repeats is called the core.
Q2. What is an AB pattern?
An AB pattern has two items that keep repeating. For example: red, blue, red, blue. 'Red' is A and 'blue' is B.
Q3. How do I find what comes next in a pattern?
First, find the core — the group of items that repeats. Then continue the core from where the pattern stopped.
Q4. Can patterns use sounds?
Yes! You can make patterns with claps, snaps, stomps, or any sounds. For example: clap, clap, stomp, clap, clap, stomp.
Q5. What is the difference between AB and ABC patterns?
An AB pattern has 2 items in the core (repeating group). An ABC pattern has 3 items in the core.
Q6. Why are patterns important?
Patterns help children think logically and predict what comes next. Pattern skills are used in maths, music, art, and science.
