How can you tell they’ve got it: Powers of Ten Notation?

If they’ve got it, you’ll see things like: Convert large and small numbers into standard form A × 10ⁿ; Convert numbers from standard form back to ordinary notation; Compare and order numbers given in standard form. Or just try it together: Can your child write 3,400,000 as 3.4 × 10⁶ and convert back — understanding that standard form is a shorthand for very large or very small numbers?

Powers of Ten Notation

Your child can write a big number like 3,400,000 in a short form using powers of ten. They can change it back to an ordinary number.

In curriculum terms

Interpret and compare numbers in standard form A × 10ⁿ where 1 ≤ A < 10 and n is an integer; convert between ordinary numbers and standard form
