Chapter 3 of the Class 4 Maths textbook Math Mela is Pattern Around Us. It explores number patterns and shape/visual patterns, and how to identify the rule behind a pattern to extend it.
Number Patterns
Q: What is the next number in the pattern 5, 10, 15, 20, ___?
A: 25. The pattern rule is “add 5 each time”, so the next number is 20 + 5 = 25.
Finding the Rule
Q: How do you find the rule of a number pattern?
A: Look at the difference between consecutive numbers in the pattern. If the difference stays the same each time (like always adding 5, or always subtracting 3), that constant difference is the rule.
Shape and Visual Patterns
Q: If a pattern of shapes goes circle, square, circle, square, circle, ___, what comes next?
A: Square. The pattern repeats in a cycle of two shapes (circle, square), so after circle comes square.
Patterns in Real Life
Q: Give one example of a pattern you might see in everyday life.
A: Examples include the repeating design on a saree border, the days of the week repeating every 7 days, or floor tiles arranged in a repeating design.
Frequently Asked Questions
What is a pattern in mathematics?
A sequence of numbers or shapes that follows a predictable rule, allowing you to guess what comes next.
How can patterns help with mental maths?
Recognising the rule of a pattern lets you skip ahead and calculate later terms quickly, without counting one by one.
