This site started out originally as a test site for the construction of online units in 'Key Skills in Numeracy' for students at the local University. These are now being delivered to students of the University via WebCT.
The units on this site have been developed further since then. If you find them useful, please be my guest. I would more than welcome any constructive criticism or feedback. Please email me on Brian Daugherty.
Thank you in anticipation.
