A large percentage of my pupils at the moment struggle with OS maps beyond merely identifying map symbols and taking grid references. To develop this, I have formulated some tasks linked to the analysis of OS map and glacial features.
There is a guess who of key features to get pupils thinking, an OS treasure hunt and a secondary task to scaffold the ability to identify the correct features. The map usage and linking it with exam style questions has worked really well so far, stretching pupils to the point of proper challenge.
