Good Books, great choices, here: The 2009 Notable Books in the Language Arts...via A Year of Reading, charming blog by "two teachers who read, a lot." One of the books on the list is by Yuyi Morales, Just In Case: A Trickster Tale and Spanish Alphabet Book.
Good time to bring up my current infatuation with the Señor Calavera video, created by Yuyi Morales (who is utterly delightful and blessedly brilliant: was lucky enough to hear her speak at remarkable Reading the World a few years ago). Yuyi has her own blog, here, and has her own Top Ten, here. SEÑOR CALAVERA has his own site, here. There's more about Yuyi at the always-amazing 7 Impossible Things Before Breakfast.
And, finally, the video: Meet SEÑOR CALAVERA.
