DD really enjoyed it. It is recommended for grade 7 and up, but I think it is very approachable and would have been good for 6th. For you, it's a bit young, but it might be worth looking for a cheap, Used Teacher's Edition as an easy read-and-then-keep. We're going to pivot a bit and do Philosophy for Kids next semester. DD wants to do Discovery of Deduction, but next year is a bit up in the air.
ETA: How sad. I booya, but only on an educational post. That's wrong.
Nonetheless:
Booya bells, booya bells,
Ringing in my head.
Oh, what fun it is
To write
A silly song like this!
This is the thread that never ends... (for Renai, who started this top o'the page tradition!)
