How about giving your mom a subscription to a personal finance magazine such as Money or Kiplinger's Personal Finance? There are also some great books she could read, such as "Your Money or Your Life" by Vicki Robin and "The Millionaire Next Door" by Thomas J. Stanley. You could also consider a financial planning session with a certified financial planner to help her map out her future financial goals and strategies. Additionally, you could gift her a personal finance app like Mint or PocketGuard to help her manage her finances on the go.
Or you can get her a star map with an important date you share.
