Lesson Overview
About this worksheet
Scientific notation writes a number as a value between 1 and 10 times a power of ten, a compact way to handle very large and very small numbers. This worksheet shows how a positive exponent makes a number larger and a negative exponent makes it smaller, then has students convert numbers both ways.
The reference box and Section A are on page 1. The reference box explains scientific notation with a large-number example and a small-number example. Section A has six numbers to rewrite. Section B on page 2 has four word problems set in science contexts.
Page 3 is a complete answer key with answers for every item. The worksheet pairs well with the Exponents and Powers of Ten worksheets.
