Lesson objective: Solve problems using equivalent fractions for whole numbers.

This lesson provides an opportunity for students to apply their knowledge and understanding of generating equivalent fractions for whole numbers to a mathematical situation. Students are asked to find the total number of days each LearnZillion friend will take to knit a scarf, given the fractional amount of the scarf each friend will knit each day.

Key Concept students will use:

- Whole numbers can be named as fractions, and naming whole numbers as fractions does not change their values.

Skills students will use:

- Use a unit fraction to partition a number line. (Grade 3, Unit 4)
- Generate an equivalent fraction for one whole.
- Generate an equivalent fraction for a whole number other than one whole.

Students engage in Mathematical Practice 4 (model with mathematics) as they represent fractions on number lines and as numbers. Students will use unit fractions to partition number lines and rename the whole numbers with the equivalent fractions that are generated.

**Key vocabulary: **

- equation
- equivalent
- number line
