Lesson objective: Apply the ability to write a nonunit fraction as a product of a unit fraction and a whole number in order to solve a realworld problem involving running on tracks.
This lesson provides an opportunity for students to apply their knowledge and understanding of multiplying unit fractions by whole numbers to a reallife situation. Students are asked to determine the length of four tracks of different lengths, given the distance someone has traveled in a certain number of laps. Once students know the length of the track, they determine how many laps are needed in order to run \(\frac34\)mile.
Key Concept students will use:

A fraction a/b is a multiple of 1/b.
Skills students will use:
 identifying the unit fraction that is a multiple of a nonunit fraction
 identifying the number of unit fractions in a nonunit fraction
 finding equivalent fractions (Grade 4, Unit 5)
Students engage in Mathematical Practice 1 (make sense of problems and persevere in solving them) as they work to solve a multistep word problem. Students identify a unit fraction, find an equivalent fraction, and determine how many times to multiply the unit fraction in order to generate the equivalent fraction.
Key vocabulary:
 denominator
 equivalent fraction
 nonunit fraction
 numerator
 unit fraction
 whole number
