Year 9 Standard Form worksheets for Year 9 Maths (Key Stage 3). Students aged 13–14 learn how to write numbers in standard form and convert between ordinary numbers and standard form notation. Standard form is a way of writing very large or very small numbers as a number between 1 and 10 multiplied by a power of 10. For example, 5 x 10³ is in standard form, what is this as an ordinary number? The answer is 5000. 0.5 x 10³ is not in standard form however, because the first number is not between 1 and 10. Can you write 0.5 x 10³ in standard form?
