Understanding the tasks
Rating the tasks
This lesson contains a few activities. Each activity will have one or more tasks. These tasks have been given a rating.
Some of the tasks in this lesson are must do. These are important to help you understand the introductory ideas or skills.
Have a go at the should do tasks and reach out to your friends or teacher if you need some advice. These will usually take a bit longer to complete than must do tasks.
Could do tasks will probably take you some extra time and might need you to get creative or problem solve. We strongly encourage you to try these.
Activity 1 - How many ice cubes?
Task 1
The following numbers can be found on the double page spread (2 pages) of 'How many ice cubes make an iceberg?'.
one tenth, 5, 25, 37, 58, 300, 400, 13.5 million and 16 million
Categorise the numbers by dragging each grey number tile into the correct region of the interactive Venn diagram.

Conventions for writing numbers
In Australia, the convention for writing numbers of more than four digits requires that numerals have a space (and not a comma) to the left of each group of three digits when counting from the left, eg 16 234.
No space is used in a four-digit number, eg 6234.
Task 2
Work through the interactive presentation below to explore estimates and a process for answering some big questions.
Note: When you have finished the task use the blue Export text button to download a copy of your answer to the last question. You can share this text with your teacher.
Task 3
Complete the interactive presentation to learn about rounding and results that are approximately equal.
Activity 2 - Calculator skills
Task 1
Use a calculator to help you match each calculation with the correct answer by completing the drag and drop interactive.
Click on the blue Submit button to assess your understanding.
Task 2
Use your calculator to answer the questions in both interactives below.
Don't forget what we have recently covered about the conventions to use when writing large numbers, including scientific notation.
Task 3
Complete the embedded interactive, Standard Index Form Matching, to test your ability to match each scientific notation calculation with its answer.
Note: There are two types of tiles, question and answer. Each question matches to its own answer.
Click on 2 cards to check if they match.
If no match occurs the tiles will be unselected.
If the tiles match they will turn green.
Hint: You may use a calculator to complete this task.

Activity 3 - Three act task
Task 1
Task 2
Do you think the three act problem above has calculated the distance incorrectly? Want to explore further?
In your exercise book or folder:
Research and record the defintions and explanations of the following terms:
velocity
graviational acceleration
initial velocity
terminal velocity.
Write a paragraph explaining why the calculation in the movie is not accurate and use the terms you researched in question 1 to explain your thinking. You might even like to explain in detail how you would make a more accurate measurement.
Handing in your work
Don't forget to hand in the work you completed today!
Your teacher will have told you to do one of the following:
Upload any digital documents you created and any photos you took of your written work to your Learning Management system (MS Teams, Google Classroom for example).
Email any digital documents you created and any photos you took of your written work to your teacher.
Make sure you keep any handwritten work you did in your exercise book or folder as your teacher may need to see these when you are back in class.
