As a retired teacher, I love this thread!
What about Pippy Longstocking by Astrid Lindgren, any of Beatrix Potter's books, Anne of Green Gables by Lucy Maud Montgomery, Little Women and Little Men by Louisa May Alcott, and any of the Classic Literature Books for kids (Treasure Island, Robinson Crusoe, Tarzan, etc.)
On our independent 2-month rail trip around England 2 years ago, we spent a week in the Lake District, and visited Beatrix Potter's farm and a museum along Lake Windemere (can't remember which town it was in now).
We have also visited Lucy Maud Montgomery's house of green Gables when we were in Prince Edward Island as we took a trip through eastern Canada. Her life is just as interesting as her character, Anne. She, Ms. Alcott, and Laura I. Wilder all used their own personal life experiences as the basis for their books. This past fall, we traveled to New England and visited "The Orchard", Ms. Alcott's home where she wrote Little Women. We also visited Sleepy Hallow Cemetery in Concord, Mass. where she is buried. I had not realized what a pilgrimage her grave was for young college women wanting to be authors---pens, pencils, stories, poems, manuscripts, coins, letters---all covering her grave. My eyes teared up reading some of those notes to her. Near her grave was Thoreau, Emerson, and Hawthorne.
I would like to put forth the idea of e-books from the library. That's what I'm doing now. Not only is our library physically closed but working on-line here in Riverside (southern California), I have been quarantined to my home for 2 weeks. My husband and I are over 65--he is diabetic and asthmatic. We both had various doctor, medical, and pharmaceutical appointments at Kaiser Medical Offices last week. This week we were notified by phone from Kaiser that "someone in your household" has recently been exposed to the coronavirus. Because of confidentiality they would NOT say who, where or how. We don't know if was a medical worker (including the assistant who put several drops in my eye) or another patient. We don't know which one of us was exposed. We were told to stay in our house and if we start having symptoms to NOT go to Kaiser, but to call a number they gave us. Luckily, I had just cooked up a HUGE pot of homemade soup which will last us a week. Our pantry of canned goods should last us through the next week.
So we are spending time reading e-books on our Kindles. Watching TV is just too depressing. I hope you will enjoy spending internet time with your grandkids and the multitude of stories you will share!!!
