Design Department
Activity Focus: Organising Information
1. Make 3 boxes for your team.
2. Calculate the amount of paper needed,
the amount of wastage, and the volume
of each box.
3. Choose an appropriate way to organise
your information
4. Provide a justification for why each box
may be suitable for packaging chocolates
5. Extension: Calculate the cost of each box design
 The box:
Each cm2 of cost $0.01
 The lid:
Each cm2 of cost $0.10
Checklist

Wrapping Department
Activity Focus: Accuracy of Calculations
Each box is gift wrapped with a ribbon
1. Make 3 boxes for your team.
2. Calculate the amount of ribbon needed
to wrap each box if an additional 20cm
is used each time for a bow at the top.
3. Choose an appropriate way do organise

Number Fluency Activity: Four 4’s
(10 minutes)
Using Four 4’s and any combination of the standard mathematical
operations make the answers from 0 to 9.
4+4–4–4=0
Example:
and
4 X 4 – (4 + 4) = 8
