Quick summary: Students collect junk mail from home and bring it to the class to investigate mathematically. Students participate in a range of mathematical activities around their junk mail, including counting the number of pieces of junk mail collected, weighing the mail, measuring the length and area the mail covers. The class will then make their own ‘no junk mail’ sign to take home.
- Students know what junk mail is and why it is used.
- Students recognise the environmental impacts of junk mail.
- Students know some actions they can take to reduce the negative impacts of junk mail on our environment.
- Students know a range of ways we can use maths to measure real world objects.
