Good morning Barbara,
Depending on her age and what she likes to touch, you have many options. Here are some of the ones I have still have pictures of, you can also search fidget quilts on the QB and find other styles.
The square one is the size of a large coaster 5-6 inches and the others about a place mat size. Size is up to you, just have fun sewing different things together,
You are a great friend.
