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 - Metric units
Task 1
Explore the double page spread, "How many sandpits in the Sahara Desert?".
Visit all six hotspots and read the information on units of measurement and large numbers.
Use this information, and your general knowledge, to answer the five questions below.

Activity 2 - Choosing appropriate units of measurement
Task 1
Complete the two slides of questions to demonstrate that you know which units of measurement are appropriate when talking about measurement.
Task 2
Complete the embedded interactive, All in a jumble, to test your knowledge of units of measurement.
Move the number and unit tiles (in columns 2 and 3) in the table to the correct column and row until all the measurements match up sensibly.
Hint: The number tiles need to be moved to the second column and the unit tiles to the third column.
Vocabulary you might see in this actvity:
crisp is a potato chip

Activity 3 - More big questions
Task 1
Complete the interactive to practise the types of calculations you will need to do to answer your big question.
Notice that each of these big questions use non-standard unit of measurements in the answer.
For example:
scales
spots
drops.
In general, we will use metric system units for our assumptions and calculations, and non-standard units for our answer.
