AO LIfepacs and Living Math? Flash cards?

Is anyone using AO lifepacs? Would doing living math along with those work? I was advised to put my daughter in something that had more repetition because she is really struggling to process certain concepts. She is i 3rd grade and is just getting into 10’s place value. She has can do a little mental math with simple addition, but she has not memorized the facts. She still uses manipulatives. I’m definitely heading into some living math, but wondered if I should continue using the lifepacs, or if that would be a hindrance. My daughter doesn’t mind doing some work pages like that if she is grasping the concept. So, my idea is to use living math to help her learn the concepts and use the lifepacs for practice. Do you think that is a good plan.

Also, does CM implement any flashcard use? I am going to begin using some living math on Monday and just wondered if I should use them at all.
