Numeracy Display on the Door

This term my school's Numeracy Team set up a little competition for a Numeracy Display. This is the second one actually. At the end of last year each faculty had to put up a display about Numeracy in our subject area.

This time the challenge was to pick a classroom door and decorate it with numerical facts or information relating to our subject area and the room number.

Here's my door, courtesy of my year 9 class:

 The secondary idea here is that we'll work towards having displays like this on all the classroom doors, not only promoting numeracy, but making it easy for new students to find their rooms!
