Lift Buttons
Thursday, 05 January 2012
Whilst often used as a textbook example, I had never seen negative numbers used in a lift before.

I thought I was the only maths person interested in lift buttons! I’ve collected photos of ones with numbers ordered in all sorts of different ways (right to left in pairs fom top to bottom, left to right from bottom to top etc). The purpose of my lift button photos is to show teachers of early numeracy the importance of making mathematical structures explicit to their kids. They can’t assume for example, that young kids know how the numbers are arranged in a hundreds chart, along a number line or around a clock face. We forget that although these structure are second nature to us, they’re not for young kids. When the numbers on lift buttons are ordered in ways we don’t expect, we’re lost. Does anyone else have photos of interesting lift button arrangements?

Heather, you might want to go for a wander through Flickr, a search for lift buttons and elevator buttons return lots of pictures.
