How do I find activities that will occupy my mother-in-law who just moved in after her husband died?

She's bored and new in our home. She reads some and watches TV, sleeps a lot. My husband I both work full-time. We have a wonderful lady who comes at lunch and stays a couple of hours. She is chatty but says Mom sleeps most of the afternoon. We are home most of the weekend and take her to church when she feels like going, which almost every week. She's been living with us about 3 1/2 months, ever since my father-in-law died. We live about 45 minutes from where they were, so she's out of her home, away from her neighbors and more than a little unsettled. Usually she handles herself well, but has some dementia and deafness. These lead to communication problems and hurt feelings. She can't always communicate what she wants to do. We want her to be happy but neither one of us is "entertaining". We are quiet people with quiet hobbies and she wants lots of conversation and... not sure what else. I'm floundering! The grandmother I grew up living with was bright and active and busy right up to the end of her life. She entertained us! I would love some ideas and suggestions.
