I usually say I don’t know how it took me so long when I finally organise one of my worksheets pages, but in this case it is almost certainly because so many of the worksheets, songs etc practise a mix of prepositions (not necessarily a bad thing). Still not able to think of a better solution, I organised it into sections and then added a misc page.
Index pages for specific kinds of preposition
Prepositions of position activities page
Prepositions of time activities page
Dependent prepositions activities page
Prepositions of movement activities page
General/ mixed prepositions
