'Squaring Decimals' worksheet

Key stage:  KS 2

Year:  Year 5 11+ worksheets

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.



Work out (0.3)2



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
