I've read about this a lot of other homeschool blogs and certain forums. I'd like to share my concept of snack/tea time.
I like to make something that has a little bit of lag time from preparation to eating. Today the menu featured homemade blueberry, banana, chocolate chip muffins.
Preparing them is a good reinforcer of math- especially since we live at high altitude and every single recipes needs altering. Every one.
Waiting as the smell fills the house is a lesson in patience. It also gives us time to work together on picking up or a cleaning project- something that can be hard to work in for some families. For us, knowing that a delicious snack is coming is a powerful motivator!
Eating together at this time is a good chance for the kids to chat, both between themselves and with me. So often we're working one on one or I am busy, but table time is a wonderful time to focus JUST on them. It's also a good chance to do fun things like practice French or use Latin.
Those are my meager thoughts.
