Pattern Around Us Class 4 Maths Chapter 4 CBSE Notes 2025-26

Jaspreet and Gulnaz organized a community lunch, or langar, in their neighborhood. They planned for about one thousand people and had the help of fifty-five volunteers for the event. The preparations included collecting donations in the form of numbers given using digits and words, such as “4 ones + 7 tens” and “ten more than three hundred twelve”. These activities helped in understanding numbers written in different ways.

Representing Numbers in Different Forms Learning to represent numbers using combinations of ones, tens, and hundreds is key in this chapter. For example, 4 ones + 7 tens is the same as 74, and “ten more than three hundred twelve” is 322. Students are encouraged to use such representations to strengthen their understanding. This skill also helps in quickly solving problems where numbers are described in words or with arithmetic expressions.

Time Slots and Counting Practice To keep track of how many people attended during different times, numbers like 52, 145, 325, and 508 were recorded. Questions focused on finding which time slot had the most or the least number of people. By using HTO (Hundreds, Tens, Ones) blocks, students learn to draw and represent three-digit numbers.

Building and Using 3-Digit Numbers Students practice making three-digit numbers using digits like 3, 5, 0, and 8, with conditions such as “numbers less than 550”. By marking these on a number line, students improve their ability to order and compare numbers. Comparing numbers visually prepares them for deeper skills like estimation and place value understanding.

Fill in the blanks exercises further strengthen understanding of how numbers relate to each other. Comparing numbers like 788 and 787, or 338 and 348, helps students spot the differences and learn the order.

The Indian Number System: Crossing One Thousand Students are introduced to reading, writing, and understanding numbers larger than 999. The Indian number system, created about 2000 years ago, enables writing even very big numbers using only ten digits. Moving from 1 to 999 and then learning to write numbers like 1000, 1001, and up to 1100 helps expand number sense.

Identifying objects or groups that have more than a thousand items (like the number of leaves on a tree or books in a library) connects large numbers to real life. This chapter uses such examples to help visualize and estimate big quantities.

Hundreds, Tens, and Ones: Grouping and Regrouping Grouping ones to make tens, tens to make hundreds, and hundreds to make thousands is an important part of this chapter. Students learn that ten ones make one ten, ten tens make a hundred, and ten hundreds make one thousand. These groupings are represented using Dienes blocks and tokens, which helps in visualizing changing numbers when tens and ones are combined or broken up.

Regrouping problems include questions like: "We are at 900. How much more to make 1000?" or "800 + ___ = 1000". Listing and filling in pairs that add up to 1000 (such as 705 + ___) gives practice in mental addition and understanding “how much more” is needed.

Grouping activities use visual aids like pictures and blocks to teach how numbers such as 34 (3 tens and 4 ones) or 250 (2 hundreds and 5 tens) are formed. Practice converting numbers between expanded form (e.g., 3 hundreds + 2 tens + 5 ones) and standard form is essential for understanding place value.

Writing and Expanding Numbers Beyond 1000 The chapter covers how numbers beyond one thousand are written with thousands, hundreds, tens, and ones. Tables show numbers like 1000 (one thousand), 1100 (one thousand one hundred), and how each is expanded (for example, 1000 + 100).

Practice exercises challenge students to sequence numbers (such as 1000, 1001, 1002, … up to 1028), increase or decrease given numbers by ones or tens, and correct common mistakes (like confusing 724 with 7024). Activities like “let us play” and “let us think” make number concepts interactive.

Place Value and Comparing Numbers Children learn to use place value tables (Th for thousand, H for hundreds, T for tens, O for ones) to identify and write numbers. Exercises include comparing numbers (using > and < signs), ordering prices, and arranging cricketer scores in increasing order. By comparing place values, students decide which number is bigger or smaller and learn clear steps for comparison.

Number line and grid activities help in locating numbers between two given points. For example, identifying which numbers fall between 2226 and 3226 or marking 1043, 1069, and 1084 on a line. These skills build confidence in estimation and visualization.

Numbers in Nature and Culture The chapter uses facts, such as the population of Indian rhinoceroses, the count of districts in India, and the number of pillars in famous temples, to show where large numbers are found in real life. By connecting numbers to cultural and environmental facts, students are encouraged to see the value of maths outside the classroom.

Using Arrow Cards and Finding Number Patterns Arrow cards represent digits for thousands, hundreds, tens, and ones. For example, building the number 3452 using cards for 3000, 400, 50, and 2 demonstrates expanded form. Students practice forming numbers given in words or as combinations and are challenged to create as many four-digit numbers as possible using selected digits, learning both patterns and permutations.

Finally, the chapter uses real-world examples like arranging mountains by height or sorting numbers in tables and grids to make learning practical and fun. By engaging in these activities, students become confident in identifying, comparing, ordering, and writing numbers up to and beyond 1000, mastering both the concepts and real-life applications.
