Unit 9, Lesson 17
Designing a 5K Course
Accelerated 6
17.1
Activity
Make a Proposal
Standards Alignment
Building On
Addressing
7.G.1
Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
7.RP.A
Analyze proportional relationships and use them to solve real-world and mathematical problems.
Building Toward
Your teacher will give you a map of the school grounds.
-
On the map, draw in the path you measured earlier with your trundle wheel and label its length.
-
Invent another route for a walking course and draw it on your map. Estimate the length of the course you drew.
- How many laps around your course must someone complete to walk 5 kilometers?

Addressing
7.G.1
Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
7.RP.3
Use proportional relationships to solve multistep ratio and percent problems.
Building Toward
- Measure your proposed race course with your trundle wheel at least two times. Decide what distance you will report to the class.
- Revise your course, if needed.
-
Create a visual display that includes:
- A map of your final course.
- The starting and ending locations.
- The number of laps needed to walk 5 km.
- Any other information you think would be helpful to the race organizers.
