Teaching guide

What students learn

Solve problems with very small and very large measurements, time scales and intervals written in scientific notation.

How to teach it

Write very large and very small measurements in scientific notation, line up the powers of ten when comparing, and use it for time scales and intervals.

Worked example
Write 440,000,000 in scientific notation.
Answer: 4.4 x 10^8
Why: Move the decimal point 8 places: 4.4 x 10^8

Generated and checked in code, so it is correct.

Watch out for

Getting the sign of the exponent wrong for small numbers, and comparing the digits without checking the power of ten.
