Lesson Purpose
Lesson Narrative
In previous lessons, students use strategies based on place value, the properties of operations, and/or the relationship between multiplication and division to find whole-number quotients with up to four-digit dividends and two-digit divisors. In previous units, students interpreted fractions as division of the numerator by the denominator.
In this lesson, students explore a real world context and apply what they have learned about division to solve problems related to the context. The context is a world record event for making the longest noodle. The mathematically important part of the context is that the noodle cannot be pieced together from separate smaller noodles. Instead, it must be rolled out as one continuous noodle. It took the employees 17 hours to roll out the approximately 10,119 ft noodle and it fed 400 people.

When students recognize mathematical features in the real world, they model with mathematics (MP4).
