Number

Unit 1 Decimals

• Can you…

• Multiply decimals

• Divide decimals

• Try a test

TOP: Review place value of decimals

Practice 1: Add and subtract decimals

Practice 2: Multiplying decimals

Practice 3: Dividing decimals

TAIL

Top Write the value of the underlined digits in the following

numbers.

• 24.5

• 364.36

• 671.846

• 5737.36

• 8467.47234

• 473.5483

Lesson

Practice 1: Add and subtract the following (remember to make sure

the decimal points are in line, especially with the whole numbers).

• 4.96 + 6.3 (2) 6.92 – 3.48

(3) 12.6 + 8.41 (4) 126.5 – 12.62

(5) 100.4 – 83.6 (6) 147.62 + 25.13 – 19.2

(7) 1596.5 + 154.258 (8) 357.25 – 159.29

(9) 657.65 + 165 – 65.28 (10) 125 – 36.52 + 12.147

Lesson

Ignore the decimal points and multiply the numbers as normal (using long multiplication where necessary), then put the decimal point back at the end. REMEMBER there must be the same number of decimal places in the final answer as there was in the whole question!)

Practice 2: Multiply the following decimals:

• 25.4  0.6

• 1.26  1.3

• 0.65  1.5

• 36.4  5.8

• 12.6  13

• 6.4  9

• 53.4  2.1

• 23.4  0.12

Lesson

Practice 3: Find the answers to the following division problems:

• 65.4  2 (2) 63.9  3

(3) 126.34  5 (4) 1.76  10

(5) 12.4  8 (6) 458.64  4

(7) 21.54  6 (8) 21.81  7

(9) 124.6  2 (10) 159.64  4
