Q8. Ascending and Descending Numbers

(i) Rearrange the given numbers in ascending order.

Ascending order means arranging numbers from the smallest to the biggest.

(a) Numbers from 51 to 100 - 1 Class 1 Worksheet Maths

Let’s look at the numbers: 70, 55, 34, 81

First, find the smallest → 34
Next bigger → 55
Next bigger → 70
Biggest → 81

So, in ascending order: 34 < 55 < 70 < 81.

(b) Numbers from 51 to 100 - 1 Class 1 Worksheet Maths

Numbers: 14, 96, 26, 69

Smallest → 14
Next bigger → 26
Next bigger → 69
Biggest → 96

So, in ascending order: 14 < 26 < 69 < 96.

 (ii) Rearrange the given numbers in descending order.

Descending order means arranging numbers from the biggest to the smallest.

(a) Numbers from 51 to 100 - 1 Class 1 Worksheet Maths

Numbers: 13, 96, 27, 68

Biggest → 96
Next smaller → 68
Next smaller → 27
Smallest → 13

So, in descending order: 96 > 68 > 27 > 13.

(b) Numbers from 51 to 100 - 1 Class 1 Worksheet Maths

Numbers: 78, 12, 15, 36

Biggest → 78
Next smaller → 36
Next smaller → 15
Smallest → 12

So, in descending order: 78 > 36 > 15 > 12.

Q10. Choose the correct option.

Only one of the following statements is correct. Tick (√) the correct one.

(a) 26 can be expressed as 2 ones + 6 ones.
(b) Expanded form of 26 is 2 + 60.
(c) 26 = 2 ones + 60 ones.
(d) 26 = 20 ones + 6 ones.
Ans: (a) 26 can be expressed as 2 ones + 6 ones → Wrong, because 2 ones + 6 ones = 8, not 26.
(b) Expanded form of 26 is 2 + 60 → Wrong, because the tens and ones are mixed up here.
(c) 26 = 2 ones + 60 ones → Wrong, because that makes 62 ones.
(d) 26 = 20 ones + 6 ones → Correct, because 20 ones = 20 and 6 ones = 6, and 20 + 6 = 26.

So, the correct answer is (d) 26 = 20 ones + 6 ones.

Other topics include writing numbers in standard and expanded forms, comparing numbers, arranging numbers in ascending and descending order, and matching related items.
2. How can I practice writing number names for numbers between 51 and 100?
Ans.To practice writing number names for numbers between 51 and 100, you can create flashcards with the numbers on one side and their corresponding number names on the other. Additionally, you can use worksheets that require you to fill in the number names or write them out in sentences. Regularly quizzing yourself and using educational games can also help reinforce your understanding of number names.
3. What strategies can I use to identify missing numbers in a sequence?
Ans.To identify missing numbers in a sequence, start by looking at the pattern in the numbers given. Check if the sequence increases or decreases by a consistent amount. For example, in a sequence like 51, 52, __, 54, you can see that the numbers increase by 1. Thus, the missing number is 53. Practicing with different sequences and using number lines can further enhance your ability to spot missing numbers.
4. How do I compare two numbers effectively?
Ans.Effective comparison of two numbers involves determining which number is greater, lesser, or if they are equal. You can use number lines to visualize their positions or simply remember that a number with more digits is typically larger. For example, 75 is greater than 62 because it is further along on the number line. Practicing with various pairs of numbers will help improve your comparison skills.
5. What is the significance of writing numbers in standard and expanded form?
Ans.Writing numbers in standard and expanded form helps to understand the value of each digit in a number. Standard form represents the number as it is, while expanded form breaks it down into the sum of its parts based on place value. For instance, the number 76 in expanded form is 70 + 6. This practice reinforces place value concepts and aids in comprehension of larger numbers, making it easier to perform arithmetic operations.
