About this worksheet

Converting between standard and scientific notation is a test-day staple in every state. The generator varies magnitude in both directions — big numbers and small decimals — so students practice counting the decimal moves both ways.

Students shaky on the skill itself? Send them to the free lesson: Scientific Notation — explained step by step.

Want this in multiple choice? Harder numbers? 30 versions?

Built for math teachers. Andy generates custom worksheets across Pre-Algebra, Algebra 1, Geometry, and Algebra 2 with exact answer keys.
