First Grade Math Worksheet and Activities, Place Value and Numbers

Friends, we have presented this post’s topics of First Grade Math Worksheet and Activities in a beautiful and simple way. Let's learn all the topics step by step with examples and solutions so that students can get 100% proficiency from this lesson. Here, in Part 1 of the First Grade Math Worksheets and Activities, various topics on Place Value and Numbers are discussed. Let’s get started. It is worth noting that the PDF link to the complete lesson (with pictures) of the First Grade Math Worksheets and Activities is given below along with this lesson.

Math Place Value

One-digit numbers	Two-digit Number
0-9	10-99

Let us look at the number 85.

Tens	Ones
8	5

Here, 8 tens = 80; the place value of 8 is 80.

5 ones = 5; the place value of 5 is 5.

Learning outcomes of place value:

(i) The place value of each digit depends on its position, for example, if it is in the ones place, its value will be different from if it is in the tens place or others.

(ii) But a digit’s face value is same as the digit itself.

Understanding Face Value and Place Value:

Tens	Ones	Face Value	Place Value
6	7	6	60
8	5	5	5
5	9	5	50
2	5	2	20
5	1	1	1
9	5	9	90

6	3	3

Answer:

Tens	Ones	Face Value	Place Value
1	7	7	7
2	8	2	20
3	9	3	30
4	1	1	1
5	2	5	50
6	3	3	3

2. Observe the numbers and find the place value of the red-colored digit considering its face value.

Numbers	Face Value (Red-colored digit)	Place Value

The Number 100

Let’s Know:

1-digit smallest number	0
1-digit greatest number	9
2-digit smallest number	10
2-digit greatest number	99

Result:

1-digit greatest number + 1 = 10 = 2-digit smallest number

1 + a greatest number = nest level smallest number.

So, 99 + 1 = 100 = 3-digit smallest number.

Form 99+1=100 with blocks:

□□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□  + □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□	□ □ □ □ □   + □ □ □ □	□   =	□□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□ □□□□□□□□□□

Greater or Less than and Equal to

Greater than sign is >; Less than sign is < and Equal to sign is =. We use >, < and = as per the following conditions.

Bigger number > smaller number; smaller number < bigger number; number = same number.

Example:

(a) 6 is greater than 2    

     6   >   2

(b) 5 is less than 9    

     5   <  9

(c) 8 is equal to 8    

     8   =   8

Better understanding:

2 > 1	1 < 2
3 > 2	2 < 3
4 > 3	3 < 4
5 > 4	4 < 5
6 > 5	5 < 6
7 > 6	6 < 7
8 > 7	7 < 8
9 > 8	8 < 9
10 > 9	9 < 10

We get, 10>9>8>7>6>5>4>3>2>1 and 1<2<3<4<5<6<7<8<9<10

Result: 10 > 1, 9 > 2, 5 > 3,…….. and 1 < 8, 3 < 9, 8 < 10,……….

Comparison of Numbers

Here we will compare one-digit and two-digit numbers to see which number is bigger or smaller.

(a) Compare 27 and 9.

26 has two digits.

8 has one digit.

26 is greater than 8 or 26 > 8.

(b) Compare 10 and 8.

10 has two digits.

8 has one digit.

10 is greater than 8 or 10 > 8.

Result: Two-digit number > one-digit number.

(c) Compare 93 and 59.

93 has two digits.

59 has two digits.

93’s tens place digit = 9

59’s tens place digit = 5

9 > 5

So, 93 > 59 or 83 is bigger than 59.

Result: When two two-digit numbers are compared, the number with the bigger tens place digit is greater.

(d) Compare 71 and 82

71 has two digits.

82 has two digits.

71’s tens place digit = 7

82’s tens place digit = 8

7 < 8

So, 82 > 71 or 82 is bigger than 71.

(e) Compare 37 and 36

37 has two digits.

36 has two digits.

37’s tens place digit = 3

36’s tens place digit = 3

3 = 3

37’s ones place digit = 7

36’s ones place digit = 6

7 > 6

So, 37 > 36 or 37 is bigger than 36.

Result: When two two-digit numbers are compared and they have the same tens place digit, the number with the bigger ones place digit is greater.

Comparison of Numbers Easily

(i) Compare 54 and 56

Solution:

5 = 5

4 < 6

54 < 56

(ii) Compare 9 and 99

Solution:

9 = 09

0 < 9

9 < 99

(iii) Compare 81 and 86

Solution:

8 = 8

1 < 6

81 < 86
