Activity Introduction

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.

Learning intentions:

  • 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.

Part A: Analysing junk mail

Preparation - Begin this activity by asking your class collect junk mail from home (if they have any) and bring it to school. You could do this over one week or several weeks. Also ask other staff at school to do the same so that you end up with a decent pile of junk mail that you can use in the classroom.
