The great pet debate

What? We are learning to estimate and rank numbers in order.
Why? This will help us to work out the costs of owning a pet.
How? I’ll be able to work in a just right group to complete a brainstorming activity.

Discussion: Australia has one of the world’s highest rates of pet ownership per capita: 36% of households own dogs and 23% own cats. Why do people have pets? What sorts of animals are not suitable as pets? Why? Do you think owning a pet is ethical?

After watching the video brainstorm a list of costs involved in having a pet.

  1. Estimate how much each pet might cost to buy.
  2. Write the pets in order of cheapest to most expensive.
  3. Now brainstorm a list of other costs involved in having a pet. Financial costs may include: Food, an enclosure, equipment, registration, training, kennelling, vet’s fees.
  4. Once you have done this rank the costs in order from highest to lowest.
  5. Now research using netbooks/ipads and check actual costs against your estimations.

Curing the plague! (and interpreting data…)

There’s been a plague in the Rio Olympic Village and it’s turning all the Olympians into weird monsters!

What? We are learning to Interpret data through comparing graphs.
Why? This will help us to understand how to read and compare different data sets
How? I’ll be able to complete the activity and write a quality blog comment to reflect on my learning

Click on the link above and follow the instructions to help cure the plague! (Use headphones please)

Write a quality blog comment reflecting on your learning , answering these 3 questions:

1) What are tally marks used for?
2) How many different types of graphs can you name?
3) How do graphs help us to understand data?

Spinner Experiment

What: We are learning to predict possible outcomes in an experiment.

Why: This will help us to improve our ability to make predictions.

How: I’ll be able to conduct a chance experiment using a spinner.

In pairs, you will collaborate and negotiate to design and build your own spinner online, choosing how many parts you want your spinner divided into and the colours of each part.

  1. Predict what the outcomes would be if the spinner were to spin 10 times.
  2. Spin the spinner 10 times and record the results.
  3. Describe why the results may be the same or different to their predications.
  4. Share your ideas and discuss your strategies – recording them in their maths notebooks and post as a comment below.

What influences the sector the spinner lands on? Chance or luck? Explain your answer.

3D Shapes

Use your knowledge of 3D shapes to complete the mission.

You will need headphones for this activity if completing in class.

Click here to begin the 3D Shapes Mission

(sorry but this game doesn’t work on the iPads)

After solving the mission go to the following website and explore and record the properties of 3D shapes.
3d shapes 3D Shapes interactive

Can you create your own 3D shape?

Can you create a net, print and make the 3D shape?

Were you successful making your own net? What shape did you create?

Nets of 3D shapes

Cube net

The video clip below shows a net made from Polydron. You can change the net using the drop down menu on the right hand side. When you press play, you will see the attempt to assemble the net into a solid 3D shape. Sometimes they will succeed, sometimes they will fail.

 

 

Before watching each video clip, consider these questions:

  1. Can you imagine folding the net up into a solid shape?
  2. Do you think that the net will fold into a shape with all sides clicked together?
  3. Can you imagine the shape of the final solid if the net does indeed correctly fold together?

Record your predictions and discuss with a partner before watching the the video for each net.

  1. Were you correct? Was the result a surprise in any way?
  2. Try again to imagine how the shape folded together.

Draw an accurate drawing of the net in your book. Can you see which sides joined together? Can you indicate this clearly on your diagram? Can you prove your net works?
