Class 1 Maths Worksheets Chapter 4
FAQs on Class 1 Maths Worksheets Chapter 4
1. What are the important topics in Class 1 Maths Chapter 4, Subtraction, for the 2025-26 exams?
For the CBSE Class 1 exams, the important topics in Chapter 4, Subtraction, include:
- The basic concept of 'taking away' using objects and pictures.
- Simple subtraction word problems or stories.
- Vertical subtraction of single-digit numbers.
- Creating and solving subtraction sentences (e.g., 7 - 3 = 4).
- Subtraction with zero.
Focusing on these areas will help cover the types of questions most likely to appear in the exam.
2. What is a subtraction sentence, and what kind of important questions are based on it?
A subtraction sentence is an equation that shows one number being taken away from another. For example, 9 - 4 = 5 is a subtraction sentence. Important questions for the exam often ask students to:
- Write the correct subtraction sentence for a given picture (e.g., a picture of 6 birds with 2 flying away).
- Fill in the missing number in a sentence, like 8 - __ = 3.
- Match a word problem to its correct subtraction sentence.
3. Why is it important to practise word problems for the Class 1 Subtraction chapter?
Practising word problems is crucial because they test a student's ability to apply the concept of subtraction to real-life situations, not just perform calculations. These questions check reading comprehension and problem-solving skills. In exams, they are often used to identify students who have a deeper understanding of 'why' we subtract, which can lead to higher marks.
4. What kind of picture-based subtraction questions are frequently asked in Class 1 exams?
Picture-based questions are very common in Class 1 exams as they are a great visual tool. Frequently asked questions include:
- Crossing out objects: A set of objects is shown, and students must cross out a certain number and count the remaining ones.
- Story pictures: A sequence of pictures showing a 'take away' scenario, where students must determine the final number.
- Comparing sets: Two groups of objects are shown, and a question might ask how many more objects are in the larger group.
5. How do important questions test the concept of 'taking away' using real-life examples for Class 1 students?
Exams use real-life examples to make subtraction relatable and test true understanding beyond just numbers. Important questions might involve scenarios like:
- Having a certain number of candies and eating a few.
- Balloons popping out of a bunch.
- Giving away toys to a friend.
These questions test if a student can translate a real-world situation into a mathematical operation (subtraction), which is a key skill assessed in the CBSE 2025-26 pattern.
6. How is subtracting zero from a number different from subtracting a number from itself, and why is this concept important for exams?
This is an important concept that often appears in exams to check for common mistakes. The difference is:
- Subtracting zero: When you subtract zero from a number, the number remains the same (e.g., 5 - 0 = 5). It shows nothing was taken away.
- Subtracting a number from itself: When you subtract a number from itself, the answer is always zero (e.g., 5 - 5 = 0). It shows everything was taken away.
This is important because it tests a student's understanding of the role of zero in subtraction and their attention to detail.
7. What types of important questions like MCQs or fill-in-the-blanks can come from the Subtraction chapter?
For the Subtraction chapter, exams often include various objective-type questions to test speed and accuracy. Important formats include:
- MCQs (Multiple Choice Questions): e.g., 'What is 8 - 5? (a) 2, (b) 3, (c) 4'.
- Fill-in-the-Blanks: These can be straightforward (9 - 6 = __) or require finding a missing part of the problem (10 - __ = 4).
- True or False: e.g., '7 - 7 = 7. (True/False)'.
8. Besides finding the answer, what other skills are tested through important questions on subtraction, like finding the missing number?
Questions that ask to find the missing number (e.g., 9 - __ = 5) are considered Higher-Order Thinking Skills (HOTS) questions for this level. They test more than just basic subtraction. They assess a student's:
- Logical thinking and reasoning skills.
- Understanding of the inverse relationship between addition and subtraction (a student might think '5 plus what makes 9?').
- Ability to work backwards to solve a problem.
