Class 4 Maths - ICSE
Patterns
In the Class 4 ICSE Mathematics chapter on Patterns, students learn to identify, understand, and extend repeating or growing sequences made of numbers, shapes, and letters. This chapter builds a strong foundation in logical reasoning, observational skills, and early algebraic thinking. Students explore arithmetic sequences by finding missing numbers using rules of addition, subtraction, multiplication, or division. Mastering this chapter is essential for scoring well in ICSE examinations, as it frequently features in problem-solving and reasoning sections, typically carrying about 5 to 8 marks through objective and short-answer questions.

Repeating Patterns
A sequence of shapes, colors, or objects that repeat themselves in a specific and regular order.
Number Patterns
A sequence of numbers arranged according to a rule, such as adding or subtracting a fixed number each time.
Growing Patterns
Sequences where the shapes or numbers increase or decrease in size or quantity by a predictable amount with each step.
Alphabet Patterns
Sequences formed using letters of the alphabet following a specific skipping or directional rule.
Finding the Rule
The underlying mathematical operation or visual change that connects one term in a pattern to the next.

Board Exam Info
In the ICSE Class 4 Mathematics examinations, the chapter on Patterns typically carries around 5 to 8 marks. Common question types include completing the missing numbers in a sequence, identifying the rule of a given pattern, drawing the next shape in a visual sequence, and solving word puzzles based on growing patterns.
Frequently Asked Questions
How do I find the rule for a number pattern?
Subtract the first number from the second number, or look at how much you add or subtract to get from one number to the next.
Can patterns have both multiplication and addition?
Yes, advanced patterns can use a combination of operations, though Class 4 ICSE mostly focuses on addition, subtraction, and simple skip counting.
What should I do if I cannot figure out the missing number?
Check the difference between consecutive numbers. If the difference is the same throughout, apply that same rule to find the next number.
