Numbers From Ten To Twenty: CBSE Class 1 Maths Worksheet 2025-26
FAQs on Numbers From Ten To Twenty: CBSE Class 1 Maths Worksheet 2025-26
1. What are the important question types from Class 1 Maths Chapter 5, 'Numbers From Ten To Twenty', for the 2025-26 exam?
For the 2025-26 exams, important questions from this chapter test several key skills. Students should focus on:
- Counting and grouping: Making a group of ten and counting the remaining ones.
- Fill in the blanks: Completing number sequences from 10 to 20.
- Number names: Writing the names for numbers like eleven, fifteen, etc.
- Comparing numbers: Identifying the bigger or smaller number.
- Simple addition: Adding numbers that result in a sum between 10 and 20.
2. How can a student score full marks on questions about place value for numbers 11 to 19?
To score well, you must understand that numbers from 11 to 19 are made of one group of ten and some extra ones. For example, the number 14 is not just 'one and four'. For exams, you should explain it as '1 Ten and 4 Ones'. Showing this with pictures, like a bundle of 10 sticks and 4 single sticks, is an excellent method to secure full marks.
3. What is a common mistake students make in the 'Numbers From Ten To Twenty' chapter that could lead to losing marks?
A very common mistake is confusing the order of teen numbers, especially twelve (12) and twenty (20). Another frequent error is mixing up the number names, for instance, writing 'fiveteen' instead of 'fifteen'. To avoid losing marks in the exam, it is important to practise writing and saying the number names aloud regularly.
4. Why is learning about a 'group of ten' considered a very important concept in this chapter?
Understanding a 'group of ten' is a crucial exam concept because it forms the foundation of the place value system, which is essential for all future maths. It teaches students that numbers like 13 aren't just random symbols, but represent 'one whole group of ten plus three single units'. This concept makes it much easier to understand bigger numbers, addition, and subtraction later on.
5. How does knowing numbers 1 to 9 help in answering important questions about numbers from 10 to 20?
Knowing the numbers 1 to 9 is essential because the numbers from 11 to 19 are simply a combination of a 'ten' and one of these single-digit numbers. For example, once a student understands 'ten', learning 'thirteen' is just a matter of adding 'three' (from 1-9) to it. This pattern (10+1=11, 10+2=12, etc.) is a key concept that is frequently tested and makes learning numbers up to 100 much simpler.
6. What is an important type of question that can be asked about comparing numbers in Chapter 5?
A typical exam question would be: "Circle the bigger number: 17 or 12?". To answer this correctly, first, you should check the 'tens' place. Both numbers have one ten. Then, you must compare the 'ones' place. Since 7 is bigger than 2, the number 17 is bigger than 12. This step-by-step method is important for correctly solving all comparison questions in this chapter.
7. How are addition questions typically structured for Chapter 5 in the Class 1 Maths exam?
For the Class 1 exam, addition questions in this chapter are designed to build on the concept of making a ten. For example, an expected question might be 8 + 5 = ?. An important method to solve this is to break 5 into 2 and 3. Then, you can perform the steps: 8 + 2 = 10, and finally 10 + 3 = 13. This 'make a ten' strategy is a key skill tested in exams.
