About this worksheet

What students practice

Students estimate large and small quantities as a single nonzero digit times a power of 10.
Students use rounded estimates to determine how many times as large one quantity is as another.
Students explain why a comparison based on rounded quantities may differ from an exact comparison.

How to use

Use after introducing powers of 10 and scientific notation. Have students record their rounded quantities before comparing and discuss the final estimate-versus-exact question.

Lift Lines and Snowfall: Estimates at Scale

Estimate resort records and compare quantities across powers of 10.

Summarize the Records

Round each quantity to one significant digit: a whole-number digit from 1 through 9 times a power of 10. Use these rounded values whenever a question asks for an estimated comparison.

Match each lift-ride record to its one-significant-digit estimate.
