In this lesson
In this video you'll learn about converting to and from standard form for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to convert a positive number between ordinary (decimal) form and standard form A x 10^n, keeping the coefficient A between 1 and 10.

For teachers
This GCSE Maths lesson teaches converting to and from standard form. By the end, students should be able to convert a positive number between ordinary (decimal) form and standard form A x 10^n, keeping the coefficient A between 1 and 10. It works through three worked examples and the mistakes examiners report.
