Squaring Decimals

In this worksheet, students square simple decimal numbers.

'Squaring Decimals' worksheet

Key stage:  KS 2

Curriculum topic:   Maths and Numerical Reasoning

Curriculum subtopic:   Decimals

Difficulty level:  

Worksheet Overview

When we square a number which is less than 1, the answer is smaller than the original number.

 

Example

Work out (0.3)2

 

Answer

We must calculate 0.3 x 0.3

 

We know that 3 x 3 = 9

But now we must divide each of the 3s by 10

and therefore we must divide the 9 by 100.

 

9 ÷ 100 = 0.09

 

So  0.32 = 0.09

 

Similarly  0.72 = 0.49 and 0.032 = 0.0009
