Big Number Line

Thursday, 03 April 2008 | 2 Comments

For many students, working with directed numbers (positive & negative numbers) requires the visual aid of using a number line.

So, I went looking for a large sized number line that I could put above my blackboard (yep, still using a blackboard).  I couldn’t find one from any of the educational retailers.  Fortunately I’m married to a graphic designer who created an approximately 2.5 m long × 11 cm high number line that goes from −12 to 12.

This PDF file has nine A4 pages which need to be trimmed and stuck together.  For best results, it would be worth either laminating the sheets before connecting them together or sticking them onto some board.

Thankyou, Thankyou I had just about given up on finding one of these (directed number line) and saw your site and thought I will just have a quick look before I shut down. I too still have a black board! Cheers!
