This is a super handy chart (I have it as a poster in my room and also hand out a card stock copy to students) I made to help students remember and correctly use case after prepositions. It includes their definitions and usages in the chart as well.
The chart is a Venn Diagram of Dative, Two-Way (Wechsel) and Accusative Prepositions.
In the corners of the chart I have article change reminders and underneath I remind them of when to use the dative or accusation of the Two-way preps.
Students have actually come back to me from prior years to request another copy because they found it so useful!
