SEE-THINK-WONDER

1. What do you see?
2. What do you think about that?
3. What does it make you wonder?

This information comes from this amazing artist.

(you could also try this page)

Let’s say you’re in charge of the trip. How will you organise it and how much will it cost?  You can download this handout to get started with the steps below.

Transportation

Going by train

1. What day of the week would you like to take your day trip?
2. Are you going on a weekday, weekend or holiday?
3. What trainline will you use?
4. Choose a time you’d like to leave using the CityRail Timetable.
5. Are there any service changes for that day?
6. What time do you expect to arrive in Sydney?
7. How long will the trip take?
8. How many people are travelling with you?
9. Calculate the cost for your family: Use the CityRail Calculator.
10. Do you qualify for family or other discounts?
11. Add how much more will it would cost if someone in your group doesn’t do the right thing? (add this amount to the total).
    

Going by car

1. What’s the fuel consumption of the car your family would take? This is usually measured in litres/100 kilometres. Use the “Specifications” section of this page or try the Australian Green Office site.
2. How much does fuel cost today in Sydney? - Make sure you choose the fuel type that goes with your car.
3. How much did your type of petrol cost in 2002?
4. If the trip to Sydney is 100 kilometres, how much fuel will you use?
5. What is the total cost for fuel for the trip to Sydney and back?
6. Now add the cost for parking in Sydney.
7. Add the toll for using the Motorways. You will encounter two tolls going (the M5 & the Eastern Distributor) and one coming back (M5). What is the total?

Summary

Would it be cheaper for your family to travel by car or train?

Good to get together again. How are my favourite Number Crunchers?

This week we want to help each other by getting a really good set of links on help pages:

• Pythagoras’ Theorem
• Percentages
• Algebra
• Area and Volume
• Geometry
• Circles
• Ratios & Rates

Mr. March will have you logged in so that you can edit and add to one of the pages above. You might work solo or in pairs, but check first so we know who’s doing what.

Your task is to

1. surf through the links on your page
2. delete any that are broken or no good
3. add a good description to the ones you keep
4. Save the page.

Hint: if you finish with the task, take a look at the Text Book’s Web site and BrainPop Maths site for some good interactive quizzes and lessons and add them to your list.
Cool. See Mr. March or Ms. Culey if you need help.

1. Review the “Student Teams” page (listed to the right or click the link) and update your interest statement or add some good links.
2. Identify your main maths approach. This will be something like the formula for finding averages, or factoring ratios, or using an online poll, or listing data in a speadsheet.
3. Send this information to the Weblog as comments or as a post after you register.

You can use this page to explore links or try a Alexa search
