Quick thought with respect to reading comprehension: do you still have her read out loud to you? And do you read out loud to her? It's easy when you have a great reader to let them go independent, but reading together is a great way to slow down and talk though all the new vocabulary and concepts, rather than her skipping over them.
A sneaky add-on is switching which parent's turn it is to read each night - thus requiring the child to summarize what the parent missed the previous evening. For your DD, perhaps you could try asking for the most important thing(s) that happened, rather than a detailed summary?
