Reading, Writing, & Spelling: Talk to your spouse in secret code. It will drive your older kids crazy and improve their vocabulary.

Example: Dad: "Do you want to go get some frozen bovine lactation?"

Mom: "Maybe."

Kid: "I DO, I DO! What is it?"

Dad: "Figure it out and I'll give you double!"

Kid:"Where's the dictionary?"

Next night:

Mom: “Tonight we are having legumes. Do you want double?”

The kid, remembering the frozen bovine lactation, says,

“Yes! I would love double!”

At dinner the kid says: “Hey, why do I have so many beans on my plate?”

Mom laughs and says, “You said you wanted a double portion!”

Now the kid is looking up words to use on Mom!
