LOL - My DH husband teased me about being like this even before DS12 was born. There was my 'Passive Solar Energy' Phase, and my 'Rewriting Nursery Rhymms' Phase. I was so in Gifted Denial at the time!
I've come to call it the 'Unit Studies' approach, with a nod the the homeschoolers who do things this way.
I've also read one paper that posited that there were 'Accelerative Gifties' and 'Encrichmentive Gifties' with the EGs being block learners, and the AGs not really being emotionally involved with choosing what they are learning, just wanting the pace and level correct. With that one paper I understood myself and DH SO much better. That was a long time ago, and I have know idea who I'm misquoting, but would love it if anyone has that info.
