NCERT solutions for Class 3 Mathematics Chapter 12 Give and Take – complete answers & explanations
Class 3 Mathematics Chapter 12, Give and Take, introduces students to the fundamental concepts of addition and subtraction through engaging real-world scenarios and numerical patterns. This chapter is important because it builds a strong foundation for mental arithmetic, understanding currency, and recognizing how numbers change when we add or subtract specific values. This blog provides complete NCERT solutions strictly based on the worksheet to help students master these essential mathematical skills.
What this NCERT chapter covers?
1. Identification and completion of number patterns by adding or subtracting specific values like 2, 5, 6, 9, 10, or 100.
2. Solving word problems involving the addition and subtraction of saplings, books, and students.
3. Using a number grid to perform mental addition and subtraction.
4. Understanding the value of money and using different combinations of notes and coins to make specific amounts.
5. Estimating sums and differences to the nearest 100 and comparing numerical expressions using greater than or less than symbols.
How to use these NCERT solutions?
1. Students should first attempt to solve the worksheet questions independently to test their understanding.
2. Use these solutions as a reference to check the accuracy of your answers and understand the steps involved.
3. Parents and teachers can use this guide to explain the logic behind number patterns and currency exchanges.
4. These solutions follow the worksheet order exactly, making it easy to navigate through different sections like "Let Us Do" and "Match The Following."
Important tips & tricks for students
1. Pay close attention to the "Rule" in number patterns; always check if the numbers are increasing (addition) or decreasing (subtraction).
2. When working with money, try to break down large amounts into smaller denominations like 100s, 50s, 20s, and 10s for easier calculation.
3. For estimation tasks, remember that "nearly" means rounding the final answer to the closest hundred.
4. Read word problems carefully to identify keywords like "plus," "minus," or "exchanged" to decide which operation to use.

Questions and Word Problems
1. 364 Saplings + 52 Saplings = 416 Saplings
2. Kishan has 230 - 75 = 155 saplings now.
Pattern following Kishan's saplings: 155, 160, 170, 180, 190, 200, 210, 220 (Rule: -5)
• 456 - 63 = 393
• 309 + 80 = 389
• 270 - 36 = 234
Let Us Do
• 234 boys + 156 girls = 390 students
• 356 Books - 138 Books = 218
• 305 Sacks - 210 Sacks = 95 Sacks

Explanation:
Discuss why people exchanged different quantities based on value and need. Understand that different items have different worth. We get less milk bottles than pomegranates for Rs 100. So, naturally milk bottles cost more.
Note Things you can buy

• 205 + 215 = 420 Rs nearly 400 Rs
• 500 - 395 = 105 Rs nearly 100 Rs
• 765 - 567 = 198 Rs nearly 200 Rs
• 505 + 405 = 910 Rs nearly 900 Rs
Circle the greater one.
• 240 + 10 > 204 + 10
• 900 + 9 < 890 + 60
• 345 - 45 > 345 - 54
• 800 - 8 > 700 - 8
Find pairs that are equal
• 516 + 100 = 616 = 816 - 200
• 615 - 200 = 415 = 400 + 15
• 350 + 50 = 400 = 450 - 50
