Class 4 Maths - BIHAR
Pattern Around Us
The chapter 'Pattern Around Us' in Class 4 Mathematics introduces Bihar Board (BSEB) students to the magical world of shapes, numbers, and designs that repeat in a specific order. Students learn to observe their everyday surroundings, such as floor tiles, clothing prints, and nature, to identify repeating sequences. This chapter builds critical thinking, logical reasoning, and observational skills. In BSEB exams, it holds good weightage through objective and drawing-based questions, testing the student's ability to extend number patterns and complete geometric shapes.

Visual Patterns
Designs or pictures that repeat in a specific order, like leaf prints, flower arrangements, or shapes on a wall.
Number Patterns
A sequence of numbers that follow a specific rule, such as adding or subtracting the same number each time (e.g., 2, 4, 6, 8).
Repeating Shapes
Geometric shapes like triangles, squares, and circles arranged in a repeating order to form a continuous design.
Tiling (Tessellation)
Covering a floor or flat surface with shapes completely without any gaps or overlapping.
Growing Patterns
Patterns that increase or decrease in size or number with each step, such as adding one dot to a shape successively.

Board Exam Info
This chapter typically carries 5 to 8 marks in the Bihar (BSEB) Class 4 mathematics examination. Common question types include 'fill in the missing numbers in the sequence', 'draw the next two shapes in the pattern', and 'identify the rule in the given design'.
Frequently Asked Questions
What is a pattern?
A pattern is a design, shape, or set of numbers that repeats or changes according to a specific rule.
How do I find the missing number in a pattern?
First, find the difference between the given numbers to understand the rule (like adding 2 or subtracting 3 each time), then apply that rule to find the missing number.
Where can we see patterns in real life?
We can see patterns on floor tiles, window grills, clothes, leaves, animal skins, and even in the ticking of a clock.
