I think this might work. I've had some doubts so far, but right now, LB is working on a craft from the Kumon Book of Easy Crafts, and CC is copying a speech from As You Like It for her next memory piece.
I was sitting here working until I had to stop and take note that for at least five minutes from this week this new plan is working.
And in the time it took me to write this, CC disappeared while looking for her Shakespeare Stories by Nesbit and was found reading Calvin and Hobbes instead. At least I had my five minutes.
