2 – 1 digit – place value, unit

3 – 1 digit – place value, unit

4 – 1 digit – place value, unit

5 – 1 digit – place value, unit

6 – 1 digit – place value, unit

7 – 1 digit – place value, unit

8 – 1 digit – place value, unit

9 – 1 digit – place value, unit

ACTIVITY 2 – NUMBER OF DIGITS AND THEIR PLACE VALUES 10 – 99

10 11 12 13 14 15 up 99

10 – 1 and 0 – 2 digits – place value, Ten and Unit

11 – 1 and 1 – 2 digits – place value, Ten and Unit

13 – 1 and 3 – 2 digits – place value, Ten and Unit

14 – 1 and 4 – 2 digits – place value, Ten and Unit

15 – 1 and 5 – 2 digits – place value, Ten and Unit

Randomly choose a number on the chart and continue the flow.

For example,

26 – 2 and 6 – 2 digits – place value, Ten and Unit

30 – 3 and 0 – 2 digits – place value, Ten and Unit

44 – 4 and 4 – 2 digits – place value, Ten and Unit

78 – 7 and 9 – 2 digits – place value, Ten and Unit

89 – 8 and 9 – 2 digits – place value, Ten and Unit

92 – 9 and 2 – 2 digits – place value, Ten and Unit

99 – 9 and 9 – 2 digits – place value, Ten and Unit

ACTIVITY 3 – VALUE AND PLACE VALUE UP TO 99

1, value – 1, place value – unit

2, value – 2, place value – unit

10, value 10 and 0, place value – ten and unit

15, value – 10 and 5, place value – ten and unit

25, value – 20 and 5, place value – ten and unit

90, value – 90 and 0, place value – ten and unit

99, value 90 and 9, place value – ten and unit

ACTIVITY 3 – CONTINUATION 

Find the value and place value of 5 in

1. 5

5, value 5, place value of 5 – unit

2. 15

15, value – 10 and 5, place value of 5 – unit

3. 52

52, value – 50 and 2, place value of 5 – ten

4. 85, value – 80 and 5, place value of 5 – unit.

Continue this process with 0 – 9. For example, find the value and place of 0, 1, 2, etc. 

LESSON EVALUATION/ASSIGNMENT

ACTIVITY 3 – VALUE OF WHOLE NUMBERS 

Express 123 in expandable form. 

1       2     3   

3

20

100

123 = 100 + 20 + 3

1 Hundred + 2 Ten + 3 Unit 

OR

H    T    U

1    2     3

Therefore, the value of –

• 1 is hundred

• 2 is tens

• 3 is units

ACTIVITY – PLACE VALUE OF WHOLE NUMBERS 

1. The place value of each digit in 123.

3, 1 digit, place value – units

20, 2 digit, place value – ten

100, 3 digit, place value – hundred

The place value of each digit in 189.

9, 1 digit, place value – units

80, 2 digit, place value – ten

100, 3 digit, place value – hundred
