Running+Track

Learning Intention - To select and uses appropriate units and devices to measure lengths and distances. If you are successful in this unit you:
 * To have a clear understanding of the measurement and physical distance of a kilometre.**
 * I can choose appropriate units of measurement for length
 * I know how many metres make a kilometre
 * I can measure a kilometre and a half-kilometre
 * I use the abbreviation for kilometres (km)
 * I can select and use the appropriate unit and measuring devices
 * I can describe how a length or distance was estimated and measured
 * I can estimate lengths and distances using an appropriate unit and check by measuring

Our Question! **Currently our Cross Country track is taken up by the circus. We have been running shorter laps but many people prefer to run a single loop when running long distances to make the trip more interesting. Also, we are not really sure how far we are running which is not ideal for those who are aiming for zone or trying to improve their times.** Can you use the map below, and any measuring tools you choose, to design a new, 3km cross country track?

Some things to consider: **When we go outside of the school we need to stay within a 1km radius.** **It is best if teachers can have a good view of students, especially if some are running very quickly or very slowly.** **Is it possible to create a loop of 3km which starts and finishes at the school gates?** **You must walk when crossing the roads, and zebra crossings are best for this. How will this impact your route?** **Main roads are not the nicest to run along as the car fumes can be irritating when breathing heavily.** **Grassy areas are better to run on than pavement as the uneven ground helps strengthen your ankles and reduce shock from the hard ground.** The Gazette is asking about local parks this week. Can you design a running park / track that is - A polygon - Has a perimeter of 1.5km (so two laps would be 3km) Would a regular or irregular polygon be the most suitable? **Unsure about polygons?** Try @http://www.mathsisfun.com/geometry/polygons.html **Need a challenge?** Can you design a running track that is  - A shape where two polygons mirror each other so that if you can have two (or more?) different length tracks at the same park?
