I would agree that maximizing the services you are qualified for it the best advice. In addition, you can talk with the therapists and teachers to get specific tasks to work on when she is at home. By providing early intervention with formal services, and supplementing them at home , you will give your daughter the best chance. Good luck.
I am a Learning Disabilities teacher. Any type of learning/memory game is good. One of the game companies used to make a game called Memory that had a bunch of cards with pictures on them. You layed the card out and turned them over trying to make matches. You had to remember where you saw the pictures. Any type of memory game is good. You can put objects on a tray uncover them for so many seconds, then cover them back up and have her tell you all that she remembers. You can give her sequences of numbers and have her repeat them to you. Start out with 2 or 3 and work your way up. Give her an oral list of 2-3 items that she needs to help you remember. Gradually increase the number of items as she becomes successful. I am sure that there are computer games available for memory skills. Hope this helps.
