A Brief Overview of Chapter 5 Numbers From Ten to Twenty
One of the most important things while teaching any concept to the kids is to have an overview of the subtopics that are covered in the chapter. Since chapter 5 primarily deals with teaching kids about learning numbers, let us look at the topics and activities covered in the chapter.
Grouping the Objects
Meaningful counting is an essential component of mathematics. Understanding and operating numbers is a key skill in mathematics. The grouping of the objects will help them to consider them as tens, and the single object will be treated as a unit. The set of sticks will reinforce the Unit place.
In the first section, the student will group the objects as 10 and how it is referred to in Maths. The student has to consider the group as a single unit of 10 and count the ones as a single unit. For example, 12 oranges will be seen as a group of 10 + 2 singles.
This chapter also reinforces the concept of tens and ones. The students have to read the group as 10+ single units.
Counting from 10 to 20
In the second section, the students have to count the numbers from 10 to 20. The student will count and write the number against it. Further, they have to complete the task by filling in the number or drawing the object. For example,
12 = 10 + 2
Finally, they have to break down each number from ten to twenty in the form of tens and ones.
Comparing the Objects
The students will learn to compare the objects in numbers. A pack of 17 objects will be compared to a bunch of 20 objects. The children will learn the sequence of the number and join the dot to a number.
The students are expected to learn the sequence and identify the missing number from the list. It also covers the before or after number type of question. They will be taught to compare the numbers as bigger or smaller numbers.
Addition and Subtraction
The final section of this chapter will reinforce addition and subtraction involving numbers from 10 to 20. There are a lot of practice sums in the form of vertical sum and the word problem to reinforce the addition and subtraction using the numbers 10 to 20.

FAQs on NCERT Solutions for Class 1 Maths Chapter 5: Numbers from Ten to Twenty
1. What are the concepts discussed in Chapter 5 of Class 1 NCERT Maths textbook?
The Chapter 5 of the NCERT textbook discusses numbers from 10 to 20. In the chapters before only single digit numbers were discussed with students. Now, they would be taught to identify larger numbers, compare them and perform addition, subtraction etc methods. To read more about the chapter students can refer to the Vedantu website or app.
2. What is the tens digit and the unit digit?
The tens digit is the digit that is on the left or in the multiple of tens. And the addition to it is treated as a single unit. For example, the number 12 is 10+2, hence 10 is the tens digit as it has one tens and two is seen as a single unit. Students are taught to identify as this in the beginning.
3. Is 16 bigger than 11?
Yes, 16 is a bigger number than 11. 16 is a bigger number than 11 because the value of units in it is higher than 11. The tens digit in both is the same. Both of these numbers have one tens. What makes 16 greater than one is the value of the units. six is a greater number than one. Hence, 16 is a greater number than 11. If the value of the tens is the same, the value of units is looked at to determine the correct answer.
4. How do you compare numbers according to Chapter 5 of Class 1 NCERT Maths?
The students are taught to compare the bigger numbers the same way they were taught to compare the single numbers. By matching and using the greater than or less than signs. In the exercises, if bundles of objects or a number of items is shown on one side then the students have to match the quantity to the given numbers in the other column. They can also be asked to tell which is greater by identifying tens and units in the numbers. To practise more questions on this chapter, students can download the NCERT Solutions PDF free of cost.
5. How many tens do 68 and 89 have?
68 has six tens and 89 has eight tens.
Hence, 89 is a greater number than 68. When looking to define which number is greater than the other we look at the tens and the units digits. The tens digit is the one on the left and the units digit is on the right. Students are taught to identify numbers and understand quantity by matching the number of items to the number.
