Lesson 8. Unit 4. Grade 7 EngageNY

EngageNY6 min(s)

This Instructional Activity is a part of the Lesson 8, Unit 4, Grade 7. In this example, students learn that the percent error can only be estimated, not calculated, if the exact value is not known but is known to lie in an interval between two numbers. They show their work by substituting the appropriate values into the percent error formula. In reviewing the example with the class, the teacher should explain that the most the percent error could be occurs when the numerator is as big as possible and the denominator is as small as possible.
