Class 4 Maths - CBSE
Pattern Around Us
The chapter Pattern Around Us introduces Class 4 CBSE students to the fascinating world of repeating and growing sequences. Students learn to observe designs in floor tiles, clothes, and nature, and then identify the repeating rules that govern them. They explore number patterns, alphabetical sequences, and shape combinations. This chapter builds strong logical reasoning, spatial awareness, and critical thinking skills. In CBSE assessments, questions from this chapter are scoring and test a student's ability to spot hidden rules and extend sequences accurately, usually contributing to 3 to 5 marks in the final mathematics exam.

Frequently Asked Questions
Look at the difference between the first two numbers. If the numbers are getting bigger, check what is added. If they are getting smaller, check what is subtracted.
Look at the difference between the first two numbers. If numbers increase, find what is added. If they decrease, find what is subtracted.
Can patterns have both numbers and letters together?
Yes! Alpha-numeric patterns combine numbers and letters, where each part follows its own separate rule.
What is the difference between a repeating pattern and a growing pattern?
A repeating pattern uses the exact same shapes again and again, while a growing pattern increases in size or number with each step.
