WALT - Identify and uses tenths to make numbers

Decimal fractions

# Place value practice with tenths

We are learning to use tenths

Example: Fill in your worksheet as shown

Example: 345.6

 100 10 1 3 4 5 6

Expanded number: 300 + 40 + 5 + 6/10

# Exercise 1

What to do

1) 34.5 (2) 8.7 (3) 2.1

4) 18.9 (5) 23.8 (6) 1.6

7) 0.5 (8) 0.2 (9) 3.9

10) 15.2 (11) 15 (12) 674

13) 1023 (14) 1045.6 (15) 300.1

16) 89.4 (17) 0.9 (18) 0.3

19) 104.3 (20) 100.5

 Question 1000 100 10 1 Expanded number 1. 3 4 5 30 + 4 + ⅕ = 34.5 2 8 1 80 + 1/10 = 8.1 3 2 1 20 + 1/10 = 2.1 4 1 8 9 10 + 80 + 9/10 = 18.9 5 2 3 8 20 + 30 + 8/10 = 23.8 6 1 6 10 + 6/10 = 1.6 7 0 5 0 + 5/10 = 0.5 8 0 2 0 + 2/10 = 0.2 9 3 9 30 + 9/10 = 3.9 10 1 5 2 10 + 50 + 2 = 15.2 11 1 5 1 + 5/10 = 1.5 12 6 7 4 60 + 70 + 4/10 = 67,4 13 1 0 2 3 10 + 20 + 3/10 = 102.3 14 1 0 4 5 6 10 + 40 + 50 + 6/10 = 145.6 15 3 0 0 1 300 + 1/10 = 300.1 16 8 9 4 80 + 90 + 4/10 = 89.4 17 0 9 0 + 9/10 = 0.9 18 0 3 0 + 3/10 = 0.3 19 1 0 4 3 10 + 40 + 3/10 = 14.3 20 1 0 0 5 100 + 5/10 = 100.5

# Exercise 2

What to do:
Write the expanded numbers as a decimal fraction

 Question 100 10 1 1/10 Decimal fraction A 4 0 3 0 4.3 B 0 8 9 0 8.9 C 2 3 4 6 234.6 D 3 0 6 0 30.6 E 0 0 0 0 00.0 F 0 7 0 1 70.1 G 6 0 0 0 60.0 H 0 0 3 8 3.8 I 8 2 4 5 824.5 J 3 0 1 0 30.1 K 2 3 5 9 235.9

Exercise 3
Underline the tenths in each question

1)  34.6 (2) 78 (3) 345.9

4)  1234.6 (5) 67.9 (6) 0.012

7)  59.345 (8) 12345.8 (9) 456.67

10)  12.89 (11) 0.897 (12) 21.21

Exercise 4
Highlight the digit in the tens place

1) 24 741 (2) 18 9 32 (3) 78.043

4) 567.15 (5) 4536. 407

# Exercise 5

Add one tenth () to each of these numbers

1)  0.7 + 1/10 = 0.8 (2) 0.3 + 1/10 = 0.4 (3) 12.0 + 1/10 = 12.1

4) 24.4 + 1/10 = 24.5 (5) 12.6 + 1/10 = 12.7 (6)      168.4 + 1/10 = 168.5

7)  2145.22 + 1/10 = 2145.23 (8) 0.9 + 1/10 = 1.0 (9) 23.9 + 1/10 = 24.0

# Exercise 6

Take one tenth () from each of these numbers

1) 39.6 - 1/10 = 39.5 (2) 32.1 - 1/10 = 32.0 (3) 123.7 - 1/10 = 123.6

4) 0.89 - 1/10 = 0.88 (5) 45.6 - 1/10 = 45.5 (6) 56.1 - 1/10 = 56.0

7) 286. 2 - 1/10 = 286.1 (8) 39.1 - 1/10 = 39.0 (9) 8.2 - 1/10 = 8.0

10) 478.30 - 1/10 = 478.29

This week we have been learning about Place value and decimals. We have been identifying how to Add or Subtract the numbers.
