Hello Annie,
Here's a link to a method for learning to read rhythms. Although all the exercises are set in 4/4 they're readily adaptable to any time signature. These exercises helped me immensely, albeit a long time ago. It's really important to clap/sing these passages so they become fully assimilated. Good luck with your rhythm reading challenge.
