I’m looking at The Fallacy Detective for Makayla for 7th next year. We’ll take our time and use it for 2 years most likely then move into The Thinking Toolbox.
If you want to do logic in a solid but also very do-able way, I very highly recommend Art of Argument. It’s not a “not to miss” if you don’t plan on adding logic, but if you do, I wouldn’t miss it.
We have been doing Fallacy detective this year and I actually just decided we won’t be finishing it. I am sure it can work great for some and especially if you can go on the forum and all but we just didn’t love it. There is a new concept added every week and after a while it became too much.
My DS is 12, maybe he is just not the type or too young?
