Scientific Notation Worksheet for 8.EE.A.3

Convert a large or small number from standard notation into scientific notation.

Convert a number from scientific notation back into standard notation.

Estimate and state how many times larger or smaller one quantity expressed in scientific notation is than another.

Work through the sections in order, since each moves to a new skill (converting to scientific notation, then back to standard notation, then comparing magnitudes) rather than repeating the same task.

Use the comparison section (pages 14-15) as an assessment of whether students understand exponents conceptually, not just mechanically, since it requires reasoning about relative size rather than direct conversion.

Reserve the answer key for self-checking after independent practice, given the sheer number of items (154) in the set.

Scientific notation conversion — students convert standard numbers, both large and small, into scientific notation across multiple sections.

Standard notation conversion — students convert scientific-notation expressions back into full standard numbers.

Magnitude comparison — students state how many times larger or smaller one scientific-notation quantity is than another, matching CCSS 8.EE.A.3's estimation skill.
