Fun at Class Party! 3 Maths Chapter 10 CBSE Notes 2025-26

Class 3 students are getting ready for a big class celebration where they learn about measuring objects and comparing their lengths in a fun and interactive way. The chapter focuses on activities that make children observe, measure, and compare the lengths of classroom objects using both informal and formal methods. Students are encouraged to look at various pictures and answer questions based on their observations.

The activities in the lesson include measuring with hand spans, footsteps, paper strings, ropes, and even using common items like pencils and strips of paper to compare lengths. There are also group discussions and teacher notes to guide students towards using proper words and methods for measuring length, helping them become familiar with the difference between informal (like hand span) and formal (like meter rods) ways of measurement.

Students are shown a detailed picture of a class party and asked to spot different activities related to measurement. These include children decorating, making costumes, and comparing strings and objects around them.

• Measuring the height of doors and tables with hand spans or paper strings
• Comparing the length of ponytails among classmates
• Checking if objects can fit through a door or under a bridge
• Decorating the class board with paper strings of different colors and lengths

Children also engage in hands-on challenges. For example, they are asked to color the shortest paper string red and the longest green. These simple tasks help reinforce the skill of visually comparing lengths and thinking about how to identify which is longer or shorter.

Children learn that different people may get different measurements for the same object depending on the method and the tools they use. For instance, the measurement of a table using Leena's and Adi's hand spans might differ because their hands are of different sizes.

Students are encouraged to compare lengths using objects such as threads, ropes, and even footsteps. There is a special focus on solving practical problems, like determining if a big table can fit through the classroom door without actually lifting the table, by measuring and comparing with threads.

• Identifying which objects are shorter or longer by direct comparison
• Deciding if an object can pass through a space based on its length or width
• Recognizing that indirect measurements (like using a thread or string) can sometimes be more convenient

The chapter provides many practical activities to develop skills related to measurement. Students are instructed to cut and paste threads, draw strings longer or shorter than those shown, and even build bridges in the classroom using available objects. These activities help link the concept of measurement to everyday experiences.

There is a scenario where Shelly and Adi use objects to see if a table will fit through a door, promoting indirect comparison and critical thinking. Students also discuss what objects can't fit through the school gate, encouraging them to relate the concept to their real environment.

Games like making a bridge and guessing which classroom objects can pass under it invite children to predict, experiment, and check their answers. These playful approaches make mathematical measurement engaging and memorable. Children also practice measuring costumes and curtains needed for the class drama, learning that measuring with bigger or standard units is more efficient.

• Using paper strips, pencils, and arms to measure cloth or walls
• Ticking statements as true or false to understand bodily proportions (like "Your height is the same as your arms open wide")
• Doubling or joining strips to get larger measuring tools

Students are introduced to standard units like the metre. They use a metre rod, measuring tape, or a thread marked with knots at one-metre intervals to understand how long a metre is. Activities show how folding a one-metre strip in half gives a half-metre, and folding again gives a quarter-metre.

The idea is reinforced with clear steps:

1. Take a metre rod or tape and place it along a thread.
2. Mark knots at both ends for one metre.
3. Check repeatedly to confirm the length is exact.

Shopkeepers use metre rods to measure cloth, making this a familiar real-world connection for students. Children are encouraged to use these standard measurements for more accurate and common results.

Another key activity is measuring the height of classmates against a one-metre mark on the classroom wall. Children list who is taller or shorter than a metre and identify the tallest among the group. These comparisons give a practical understanding of measurement and help them see how height varies.

• Writing names under two lists: longer than one metre, shorter than one metre
• Circling the tallest child from a picture or a group list

Children are encouraged to look for objects around them and group them as more than, less than, or exactly one metre in length. They use tables to list objects and tick, for example, if a chair is more or less than a metre.

They understand parts of a metre by folding a strip—half metre, quarter metre, etc.—as practiced in the classroom. This enhances their ability to estimate and categorize objects by size.

Further tasks encourage students to measure objects using ropes cut to one metre, half a metre, and quarter metre; jump distances; and even estimate the height of their teachers. Children also discuss the number of cuts required to get four equal pieces from a one-metre rope and estimate how many footsteps fit into a metre.

Estimating, measuring, and checking work together to deepen the understanding of length, measurement, and comparison. Students become aware that using common, standard units ensures that everyone's measurements are consistent.

This chapter lets students experience measurement in practical, relatable ways. Through comparison, direct observation, play, estimation, and the use of standard units, children develop confidence in discussing, measuring, and understanding length. All exercises encourage teamwork, reasoning, and applying learning to real-world scenarios.
