Lesson objective: Apply scale factors to determine distances on a map given actual distances.

This lesson provides an opportunity for students to apply their knowledge and understanding of scale drawings to a real-life situation. Students are asked to determine a scale drawing and use it to create a map for a student to give to her grandparents.

Key Concept students will use:

- Scale drawings may be larger, smaller, or the same size as an original drawing.

Skills students will use:

- Proportional relationships ( Grade 7, Unit 1)
- Unit conversions (Grade 4, Unit 6)

Students engage in Mathematical Practice 4 (Model with mathematics) as they create an actual map given information about a real-life situation.

**Key vocabulary: **

- original figure
- proportional
- scale drawing
- scale factor

**Special materials needed:**

- Optional: Large sheets of paper to create maps.
