DS5 is in kindergarten with a lot of differentiation. After a month of breezing through progressively more difficult work he finally got to something challenging and he was furious. It sounds like it was reading graphs and solving problems.

DS8 was laughing at him. "School isn't just about showing up and looking like a genius on the easy stuff. They figure out what you don't know and make you learn it!"

DS5 was not having it. "The math was mixed with reading and the problem wasn't even there. I had to read and then make it myself!"

This outrage lead to destruction laced imaginative play at recess. He and his friends planted maple seeds all around the school in hopes that the trees would grow to cover the school and turn it into a jungle. There might've been magic involved too. We'll see tomorrow if it worked. 😀
