Give and Take 3 Maths Chapter 12 CBSE Notes 2025-26

In this chapter, students explore the concept of "Give and Take" through interesting stories and practical examples based on daily life. The lessons use simple activities around saplings, money, objects, and cards to help children understand addition and subtraction, and the importance of understanding numbers in hundreds, tens, and ones. Through this approach, students can relate mathematics to their surroundings, making the learning process more enjoyable and effective.

The story begins with Kishan, who runs a large nursery where villagers frequently come to collect saplings. The context provides relatable examples for practising addition and subtraction. Students encounter fun exercises that ask them to quickly add or subtract numbers like 2, 5, 6, or 9, promoting mental math skills. Lists of numbers such as 334, 336, 375, and 387 provide opportunities to recognise patterns and practice calculation.

One example problem shows that Kishan had 364 saplings. He brought back 52 more from a friend’s village. To find the total, students add 364 and 52, which gives 416 saplings. This sum is explained step-by-step using a Box Diagram representing hundreds, tens, and ones. Students are reminded to group 10 tens into one hundred, and combine hundreds accordingly. Visual aids like number lines—such as moving from 364 to 414 in tens—are recommended to help understand these concepts.

Students are encouraged to use learning aids such as Dienes Blocks and the number line to visualise the relationship between numbers. Teachers are advised to discuss the connections between hundreds, tens, and ones for a deeper understanding.

Another problem involves subtraction: Kishan needs to deliver 230 saplings, but has packed only 75. To find out how many more are needed, students subtract 75 from 230, which equals 155 saplings to be packed. This is again shown using a Box Diagram to help visualise how the numbers line up and how subtraction works with regrouping.

Several story-based questions encourage further practice:

• Kishan has 456 saplings and distributes 63; students find the remaining number.
• He has 309 saplings and receives 80 more; they add to find the total.
• Comparisons between Kishan’s and his friend’s saplings, promoting understanding of “how many more.”

Box diagrams are suggested as a method for solving these problems. Other exercises focus on subtracting and adding values, such as books and the number of boys and girls, or adding sacks, to develop proficiency in handling numbers in various scenarios.

Students are introduced to a number grid ranging from 451 up to 530 in a tabular form. With this, students can check how numbers change as they add or subtract different amounts. For example, to solve 456 + 10 or 489 + 21, students visually see which values on the grid align with their answer. Problems like 519 – 40 encourage subtraction practice and pattern recognition.

Teachers guide students to see how the digit in each place (hundreds, tens, ones) changes when adding or subtracting 100, 10, or 1. This helps students grasp how numbers are constructed and deconstructed in mathematics.

The chapter gives historical context by describing bartering in villages, where people exchanged goods like rice, vegetables, or sarees. Students discuss why different quantities were exchanged, leading to the introduction of money and its role as a medium of exchange today. They learn about notes and coins in different values and how these are used in daily life.

Practical examples show one ₹10 note buying either a Hawa Mithai or ten toffees. A comparison is made between buying milk bottles or pomegranates for ₹100. Students are encouraged to think of two different things they could buy for ₹10 and to circle which items cost more. They also practice finding combinations of notes and coins that make up equal values.

Real-life style questions include:

• How many ₹100 notes are equal to a ₹500 note?
• What items can a person buy with ₹500?
• How to draw ₹100 notes to represent a ₹500 note.

Such exercises help children handle real money situations responsibly, comparing values and understanding different ways to pay.

Engaging problems involve activities such as:

• Calculating how much Peter uncle earned from morning to afternoon by finding the difference between ₹756 and ₹465.
• Finding earnings from the sale of rice and sugar by adding ₹640 and ₹215.

Students also estimate answers, rounding to the nearest hundred, and share their reasoning in class. Additional real-life problems include:

1. Finding total earnings when an extra amount is received on another day
2. Calculating how much money to return after a purchase
3. Adding weekly savings over a period
4. Adding up different amounts saved in three months

Teachers advise students to estimate answers for sums and differences like 156 + 34 or 500 – 395, reinforcing the value of estimation and logical calculation.

Students are invited to compare similar mathematics statements and identify which are greater or if any are equal. For instance, comparing 373 + 23 with 373 + 40, or 800 – 8 with 700 – 8 helps develop number sense. Mini tables of operations (+3, -7) tied to numbers like 120 or 130 help with practicing mental math and pattern recognition.

Teachers encourage children to form and practice similar questions on their own, aiming for faster mental calculations and a confident approach to addition and subtraction.

A creative maths card game is introduced: students create cards numbered 0 to 5, form two 3-digit numbers, and then add or subtract them. Children can rearrange digits for the largest sum or smallest difference and check whose result is higher—making maths fun and interactive.

• Sample sums: 265 + 9, 405 + 56, 825 + 175
• Sample subtractions: 600 – 82, 568 – 5, 653 – 356

The chapter encourages students to use not just pencil and paper but also number cards, blocks, and classroom discussions to deepen their maths skills. Students interactively compare sums and differences, fostering healthy competition and peer learning.

Throughout the chapter, teacher notes suggest various strategies, activities, and discussions to ensure children understand why we add or subtract, the meaning behind numbers, and how maths is useful in everyday choices. Simple tools and interactive games make this an enjoyable and practical maths learning experience.
