Logic Resources before the Logic Stage: Part 2

A continuation of what we're doing with logic before beginning formal logic in 5th grade in the fall. (Part 1 here.)

Logic Resources before the Logic Stage: Part 1

While we have been doing things differently than a strictly classical education approach in the last few years, I still like to "check in" with The Well Trained Mind to get an idea of what our goals should be close to. I started Builder Boy's 4th grade year with the goal of having him ready for the classical approach for 5th grade as laid out by TWTM. Not sure if we'll actually get there or not, but I do like the idea of introducing formal logic in 5th grade. But I didn't want to just dump it on him with no warm up, so this 4th grade year we have been having some fun with various playful logic resources to introduce him to the concepts.

How Does a Homeschooler Raise a Butterfly?

I love the homeschooler changing a lightbulb joke. You know the one:

"How does a homeschooler change a lightbulb? 
First, mom checks three books on electricity out of the library, then the kids make models of light bulbs, read a biography of Thomas Edison and do a skit based on his life. 
Next, everyone studies the history of lighting methods, wrapping up with dipping their own candles. Next, everyone takes a trip to the store where they compare types of light bulbs as well as prices and figure out how much change they'll get if they buy two bulbs for $1.99 and pay with a five dollar bill.
On the way home, a discussion develops over the history of money and also Abraham Lincoln, as his picture is on the five dollar bill.
Finally, after building a homemade ladder out of branches dragged from the woods, the light bulb is installed.
And there is light."
