Another of Nik Peachey's excellent blog entries, this one included ideas for teaching and an example activity for students:
"I've found that in class most students enjoy lessons based around songs or music. More recently I've been trying to discover and develop activities that students can do online to actively engage with the vast variety of resources that are available.
