This Instructional Activity is a part of the Lesson 9, Unit 9, Grade 7. This activity examines how measurement errors behave when quantities are multiplied. In other words, if I have a measurement m with a maximum error of 5% and a measurement n with a maximum error of 5%, what percent error can m × n have? Monitor for students who use different methods to solve the problem, such as trying out sample numbers or using expressions with variables.
