For AWANA, Caleb has been working on memorizing the books of the New Testament. Thankfully, we have a CD that helps with this, and we listen to it often. He's got them down, and Meredith is actually pretty close to knowing them all as well.
Here's a quick video of Caleb reciting the NT books, in order. (Sorry for the poor video quality...I took this on my phone, and the sun was behind him. Oops.)
