This is a drag and drop version of my "match the functional group with the model" worksheet. Simply download the zip file. Unzip, open the folder and double click on the FuncDragAndDrop.html file, and you're there.
Useful as a starter round the board. Drag the models next to the correct name. If it is correct it will stick, if not it won't. This tests understanding of functional groups and different types of molecular model.
