We all want our children to be well educated.
I've come up with a few ideas to help.
Some of the basics we work on here.
Really important stuff.

Grammar:
Contractions.
You + All = Y'All
The apostrophe is inserted where the letters are missing.

Spelling:
Y'all

History:
The Civil War.
"The war betwixt the Yankees and the Americans." - Granny Clampett

Manners:
Remember to avoid any History discussions when Northern relations are visiting.
I added the above too late for the 11-yr old... Hopefully, the next visit will be better.
