We have been going the thru the book the Fallacy Detective by the Bluedorns. It has been so helpful in communication with the children. They see many of their own manipulative tactics in an effort to get their own way. (And unfortunately, a few of mine.) When these flaws in logic are uncovered the coversations and conflicts seem to be easier to resolve.
We also had a logic question that was alot of fun in our home. See how it goes in your home.
It's called the Monty Hall Dilemma. You have three cups (1,2, and 3) and under a certain cup is a coin and under the remaining cups is a rock. You are asked to pick a cup. Before revealing whether you win "Monty Hall" reveals the contents of one of the two remaining cups. It is a rock. Then asks the question, "Do you want to switch to the other cup?" Should you switch or stay with your first choice?"
I'll let you know the answer the next time I post.
