Finding 0.1, 0.01 and 0.001 - More or Less

Sep 30, 2026

Uploaded by Patrick

Use mental math to add and subtract decimals with different place values: 0.1, 0.01, and 0.001. Students solve word problems involving weights of packages, liters of chemical solution, race and swim times, lengths of boards, and measured part lengths in centimeters. Each item asks for the resulting quantity after applying the specified increase or decrease, including “more than” and “less than” comparisons to given base numbers.

FAQs

What types of math operations do the problems focus on?

They focus on mentally adding or subtracting decimals using increments of 0.1, 0.01, and 0.001, including “more than” and “less than” setups.

What context do the decimal changes appear in?

The changes are applied to real situations such as package weight, solution volume, runner or swimmer times, and measured lengths in meters or centimeters.

How is the “second value” determined in each problem?

Each question gives a starting amount and specifies how much more or less the second amount is, then asks for the resulting number.
